技术领域Technical Field
本发明涉及内窥镜透明帽技术领域，具体涉及一种可旋转的内窥镜透明帽。The invention relates to the technical field of endoscope transparent caps, and in particular to a rotatable endoscope transparent cap.
背景技术Background Art
在ESD手术的时候，切割的长黏膜由于没有支撑，容易塌陷遮挡手术视野，影响手术操作，且术后无法回收切下的部位进行病理分析。医生会使用带有固定的额外异物钳道的透明帽，伸入活检钳或是止血夹，夹住黏膜后再使用黏膜切开刀继续手术，利用新增加的辅助器械在人体内对病变黏膜进行牵拉和取出。这些操作对术者的操作水平要求较高，若是夹持角度不对，未能夹住关键部位，容易发生打滑，或是不足以将底部黏膜完整暴露，都会增加手术难度，延长手术时间，甚至容易造成病患身体的损伤。During ESD surgery, the long, cut mucosa, lacking support, can easily collapse and obscure the surgical field of view, hindering surgical procedures. Furthermore, the cut site cannot be retrieved for pathological analysis after surgery. The surgeon uses a transparent cap with a fixed, additional foreign body channel to insert a biopsy forceps or hemostatic clamp. After clamping the mucosa, the surgeon uses a mucosal incision knife to continue the procedure, utilizing newly added auxiliary instruments to retract and remove the diseased mucosa within the human body. These procedures require a high level of skill from the surgeon. If the clamping angle is incorrect, key areas are not clamped, slippage occurs, or the underlying mucosa is insufficiently exposed, the surgery becomes more difficult, the operation time is prolonged, and it can even cause physical injury to the patient.
目前的透明帽无法同时实现对额外手术器械的加入以及操作该器械的角度调整，要调整角度只能是旋转整个内窥镜或是取出内窥镜镜头重新安装调整透明帽，这会导致内窥镜丢失了病灶视野，需要重新寻找，大大增加了手术时间和操作难度，造成病人身体不适，手术效率低下。The current transparent cap cannot simultaneously accommodate the addition of additional surgical instruments and the adjustment of the angle at which the instruments are operated. To adjust the angle, the entire endoscope must be rotated or the endoscope lens removed and the transparent cap reinstalled. This can cause the endoscope to lose its view of the lesion and require a new search, greatly increasing the operation time and difficulty, causing physical discomfort to the patient and low surgical efficiency.

具体实施方式DETAILED DESCRIPTION
为使本发明技术方案更加清楚，以下结合附图及具体实施例对本发明做进一步详细说明。In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.
实施例1Example 1
结合附图1-12，一种可旋转的内窥镜透明帽，主要用于在手术过程中能够直接调整手术器械的位置，例如活检钳或止血夹在内窥镜上的位置，从而无需转动内窥镜，或者无需将内窥镜在手术过程中取出就能够调整活检钳或止血夹的位置，从而对内窥镜上的，由透明帽1、夹持装置2、控制装置3组成，夹持装置2安装在透明帽1上，控制装置3同样安装在夹持装置2的侧面，控制装置3通过连接线控制夹持装置2在透明帽1上移动，从而实现夹持装置2在透明帽1上的位置调整。In conjunction with Figures 1-12, a rotatable transparent cap of an endoscope is mainly used to directly adjust the position of surgical instruments during surgery, such as the position of a biopsy forceps or a hemostatic clamp on an endoscope, so that there is no need to rotate the endoscope, or there is no need to remove the endoscope during surgery to adjust the position of the biopsy forceps or hemostatic clamp, thereby adjusting the position of the endoscope. It consists of a transparent cap 1, a clamping device 2, and a control device 3. The clamping device 2 is installed on the transparent cap 1, and the control device 3 is also installed on the side of the clamping device 2. The control device 3 controls the movement of the clamping device 2 on the transparent cap 1 through a connecting line, thereby realizing the position adjustment of the clamping device 2 on the transparent cap 1.
透明帽1为装置的基础结构，透明帽1由内圈11、外圈12组成，外圈12套设在内圈11外侧，内圈11外圆柱形的壳体结构，外圈12为部分圆柱结构，外圈12为一个非完整圆柱，外圈12上设有缺口，外圈12的侧壁在外圈12的缺口位置直接连接在内圈11的侧壁上，外圈12的缺口位置在内圈11的底部还设有固定件15。The transparent cap 1 is the basic structure of the device. The transparent cap 1 consists of an inner ring 11 and an outer ring 12. The outer ring 12 is sleeved on the outside of the inner ring 11. The inner ring 11 has a cylindrical shell structure. The outer ring 12 is a partial cylindrical structure. The outer ring 12 is an incomplete cylinder. A notch is provided on the outer ring 12. The side wall of the outer ring 12 is directly connected to the side wall of the inner ring 11 at the notch position of the outer ring 12. A fixing part 15 is also provided at the bottom of the inner ring 11 at the notch position of the outer ring 12.
内圈11和外圈12之间设有等距的缝隙，外圈12通过在将缺口位置两侧的侧壁朝内圈11弯折并连接在内圈11的侧壁上，从而将外圈12固定在内圈11上形成稳定的一体结构。An equidistant gap is provided between the inner ring 11 and the outer ring 12. The outer ring 12 is fixed to the inner ring 11 by bending the side walls on both sides of the gap toward the inner ring 11 and connecting them to the side walls of the inner ring 11 to form a stable integrated structure.
外圈12与内圈11之间设置的缝隙用于安装夹持装置2，夹持装置2可以卡在外圈12与内圈11之间的缝隙中，从而实现夹持装置在外圈12上的移动。The gap provided between the outer ring 12 and the inner ring 11 is used for installing the clamping device 2 , and the clamping device 2 can be stuck in the gap between the outer ring 12 and the inner ring 11 , thereby realizing the movement of the clamping device on the outer ring 12 .
外圈12的缺口用于为安装控制装置3提供空间，外圈12的缺口在能够安装控制装置3且不影响控制装置3的正常使用的情况下越小越好，外圈12的缺口越小，夹持装置2在外圈12上的能够周向移动的角度越大，医护人员的调整范围也会越大，能够满足更大角度的使用需求。The gap in the outer ring 12 is used to provide space for installing the control device 3. The smaller the gap in the outer ring 12 is, the better, as long as the control device 3 can be installed without affecting the normal use of the control device 3. The smaller the gap in the outer ring 12 is, the greater the angle at which the clamping device 2 can move circumferentially on the outer ring 12, and the larger the adjustment range of medical staff will be, which can meet the use requirements of a larger angle.
夹持装置2由夹头21以及由夹头21延伸而出的夹耳22，夹耳22固定在夹头21上并与夹头21形成一体结构，夹耳22由夹头21顶端向侧面弯折而成，夹耳22与夹头21之间顶部固定连接，夹耳22主体部分与夹头21平行且夹耳22主体部分与夹头21之间还设有空隙。The clamping device 2 consists of a clamping head 21 and a clamping ear 22 extending from the clamping head 21. The clamping ear 22 is fixed on the clamping head 21 and forms an integral structure with the clamping head 21. The clamping ear 22 is formed by bending the top of the clamping head 21 to the side. The top of the clamping ear 22 and the clamping head 21 are fixedly connected. The main part of the clamping ear 22 is parallel to the clamping head 21 and there is a gap between the main part of the clamping ear 22 and the clamping head 21.
夹持装置2的夹头21通过夹耳22挂在透明帽1的外圈12上，夹耳22插入到内圈11与外圈12之间的缝隙中，夹耳22顶部与夹头21连接的一端挂在外圈12的侧壁上。The clamping head 21 of the clamping device 2 is hung on the outer ring 12 of the transparent cap 1 through the clamping ear 22. The clamping ear 22 is inserted into the gap between the inner ring 11 and the outer ring 12. The end of the clamping ear 22 connected to the clamping head 21 is hung on the side wall of the outer ring 12.
夹头21上还设有若干滚轮25，若干滚轮25平行排列设置在夹头21上，滚轮25为内嵌在夹头21上且可以自由转动，滚路25用于减小夹头21在外圈12上移动的摩擦力，滚轮25侧面与夹耳22之间保留有距离，滚轮25在外圈12的侧面上转动。The chuck 21 is also provided with a plurality of rollers 25, which are arranged in parallel on the chuck 21. The rollers 25 are embedded in the chuck 21 and can rotate freely. The rollers 25 are used to reduce the friction of the chuck 21 moving on the outer ring 12. A distance is maintained between the side of the roller 25 and the clamping ear 22, and the rollers 25 rotate on the side of the outer ring 12.
夹头21下侧与夹耳22上组合设有固定扣配合结构，固定扣用于限制夹头21使夹头21不会从外圈12上脱落，夹耳22下侧设有突出扣，夹头21下侧设有固定扣，夹头21下侧设有用于固定扣滑动的卡槽，卡槽内设有弹性硅胶片，固定扣在卡槽内向下滑动，固定扣与突出扣组合，从而将夹头21与夹耳22形成一个完成的套环结构，夹头21与夹耳22形层的套环结构套设在外圈12的侧壁上，此时夹头21不会从外圈21上脱落。The lower side of the chuck 21 and the clamping ear 22 are combined with a fixing buckle matching structure, the fixing buckle is used to limit the chuck 21 so that the chuck 21 will not fall off the outer ring 12, the lower side of the clamping ear 22 is provided with a protruding buckle, the lower side of the chuck 21 is provided with a fixing buckle, the lower side of the chuck 21 is provided with a card slot for the sliding of the fixing buckle, an elastic silicone sheet is provided in the card slot, the fixing buckle slides downward in the card slot, the fixing buckle is combined with the protruding buckle, thereby forming a complete ring structure with the chuck 21 and the clamping ear 22, the ring structure of the chuck 21 and the clamping ear 22 is sleeved on the side wall of the outer ring 12, and the chuck 21 will not fall off the outer ring 21 at this time.
弹性硅胶片保持持续的伸展力，以此能够给固定扣持续向下的推力，此时固定扣能够维持和突出扣的组合状态，从而使夹头21与夹耳22形成的套环结构无法解除。The elastic silicone sheet maintains a continuous stretching force, thereby being able to continuously push the fixing buckle downward. At this time, the fixing buckle can maintain the combined state with the protruding buckle, so that the loop structure formed by the clamping head 21 and the clamping ear 22 cannot be released.
在需要解除夹头21与夹耳22形成的套环结构，将夹头21从外圈12上取下时，仅需要向上推动固定扣，固定扣在卡槽内相上滑动，此时固定扣和突出扣解除组合状态，此时仅需要轻微向外拉动夹耳22，即可将夹头21从外圈12上取下。When it is necessary to release the ring structure formed by the clamp 21 and the clamp ear 22 and remove the clamp 21 from the outer ring 12, it is only necessary to push the fixing buckle upwards, and the fixing buckle slides on the inner side of the slot. At this time, the fixing buckle and the protruding buckle are released from the combined state. At this time, it is only necessary to slightly pull the clamp ear 22 outwards to remove the clamp 21 from the outer ring 12.
夹头21内设有上下贯穿的夹持孔，夹持孔用于安装异物钳管、手术器械，举例为夹持孔内可以安装并固定活检钳或止血夹等器械，夹持孔内设有内螺纹，夹持孔内的内螺纹上侧设有弹性硅胶垫圈28，异物钳管头部有外螺纹配合，将异物钳管插入夹持孔内，当夹持孔内的内螺纹和异物钳管上的外螺纹接触时，转动异物钳管，通过压迫硅胶垫圈形变可以控制手术器械在管道内的位置以及伸出长度的固定，方便医生操作，由于手术过程中需要器械移动的距离较小，因此通过压迫弹性硅胶垫圈28即可满足手术器械在夹头21内的移动和固定。A clamping hole is provided in the chuck 21 which runs through the upper and lower parts. The clamping hole is used to install foreign body clamp tubes and surgical instruments. For example, instruments such as biopsy forceps or hemostatic clamps can be installed and fixed in the clamping hole. An internal thread is provided in the clamping hole, and an elastic silicone gasket 28 is provided on the upper side of the internal thread in the clamping hole. The head of the foreign body clamp tube has an external thread to cooperate with it. The foreign body clamp tube is inserted into the clamping hole. When the internal thread in the clamping hole and the external thread on the foreign body clamp tube come into contact, the foreign body clamp tube is rotated. By compressing the deformation of the silicone gasket, the position of the surgical instrument in the pipeline and the fixation of the extended length can be controlled, which is convenient for the doctor's operation. Since the distance that the instrument needs to move during the operation is small, the movement and fixation of the surgical instrument in the chuck 21 can be satisfied by compressing the elastic silicone gasket 28.
夹头21具有可拆卸性，通过设计和安装不同的夹头，可以实现不同的透明帽功能。The clamping head 21 is detachable, and different transparent cap functions can be achieved by designing and installing different clamping heads.
夹头21可分为单夹头和多夹头，单夹头上仅设置有一个夹持孔，多夹头上可设置多个夹持孔，从而实现在一个夹头上安装多个器械的作用。多夹头上的结构与单夹头相同仅增加了夹持孔的数量。The chuck 21 can be divided into a single chuck and a multi-chuck. A single chuck has only one clamping hole, while a multi-chuck can have multiple clamping holes, thereby enabling the installation of multiple instruments on a single chuck. The structure of the multi-chuck is the same as that of the single chuck, only the number of clamping holes is increased.
透明头1的位于外圈12缺口位置下侧的固定件15上设有通线管孔14，通线管孔14贯穿固定件15。A wire conduit hole 14 is provided on the fixing piece 15 located below the notch of the outer ring 12 of the transparent head 1 , and the wire conduit hole 14 passes through the fixing piece 15 .

The wire tube 32 is installed on the transparent head 1. The handle 31 is connected to the end of the wire tube 32. The wire tube 32 is provided with a block for being clamped in the wire tube hole 14. The wire tube 32 can be split into two parts. The wire tube 32 after splitting consists of a block and a tube body. The block passes through the wire tube hole 14. The block part that passes through the wire tube hole 14 and extends out is fixedly combined with the tube body again to form the wire tube 32. The wire tube 32 is used to provide a pipeline structure for installing a traction rope for pulling the clamping device 2 to move on the transparent cap 1. The transparent tube 32 facilitates the handle 31 to control the pulling direction and pulling length of the traction rope.
通线管末端连接手柄31为牵引绳的动力部件，手柄31能够直接控制牵引绳的拉动方向和拉动长度，用于可以通过操作手柄31从而控制夹持装置2在透明帽1上的位置。The handle 31 connected to the end of the wire tube is the power component of the traction rope. The handle 31 can directly control the pulling direction and pulling length of the traction rope, and is used to control the position of the clamping device 2 on the transparent cap 1 by operating the handle 31.
夹耳22上设有绑线孔26，绑线孔26在夹持装置2安装在透明帽1上后，带有绑线孔26的夹耳22插入到内圈11和外圈12之间的缝隙中，此时在绑线孔26的两侧分别连接朝向相反的两个方向的牵引绳，通过拉动不同方向的牵引绳，能够带动夹耳22以及夹头21在透明帽1上朝向拉动方向移动，从而实现夹持装置2的位置调整。A wire binding hole 26 is provided on the clamping ear 22. After the clamping device 2 is installed on the transparent cap 1, the wire binding hole 26 is inserted into the gap between the inner ring 11 and the outer ring 12.

A sleeve can be provided between the intermediate shaft 313 and the handle housing 311 to realize the rotation and sliding functions of the intermediate shaft 313. The intermediate shaft 313 is installed inside the sleeve, and the sleeve does not need to slide. The intermediate shaft 313 only needs to slide relative to the sleeve. The sleeve and the intermediate shaft 313 are keyway matched. When the intermediate shaft 313 rotates, the sleeve is synchronously driven to rotate. At this time, the intermediate shaft 313 can be rotated relative to the handle housing 313.
中间轴313上设置有两个并列设置的棘轮314，两个设置在手柄壳体311内部的棘轮314分别设置在中间轴313的两侧。Two ratchet wheels 314 are arranged in parallel on the intermediate shaft 313 . The two ratchet wheels 314 arranged inside the handle housing 311 are respectively arranged on both sides of the intermediate shaft 313 .
手柄壳体311内部设有位于中间轴313两侧转动设有与两个棘轮314分别配合的内啮合齿轮315，位于两侧的内啮合齿轮315同样为不同方向的内啮合齿轮且与两个棘轮314的方向对应设置。Inside the handle housing 311 , there are internal meshing gears 315 located on both sides of the intermediate shaft 313 and rotatably engaged with the two ratchet wheels 314 . The internal meshing gears 315 located on both sides are also internal meshing gears with different directions and are set corresponding to the directions of the two ratchet wheels 314 .
两个棘轮314仅能够其中一个棘轮314与一个对应的内啮合齿轮315啮合，用户可以通过滑动中间轴313的方式选着需要位于两侧任意一侧的棘轮314与对应的内啮合齿轮315啮合，旋钮312用于方便用户拉动中间轴312和转动中间轴312，旋钮上设有弧形横杆，方便用户手指施力拉动中间轴312。Only one of the two ratchet wheels 314 can engage with a corresponding internal gear 315. The user can select the ratchet wheel 314 on either side to engage with the corresponding internal gear 315 by sliding the intermediate shaft 313. The knob 312 is used to facilitate the user to pull and rotate the intermediate shaft 312. An arc-shaped cross bar is provided on the knob to facilitate the user to apply force with his fingers to pull the intermediate shaft 312.
牵引线由通线管32引入到手柄31内，引入到手柄31内的两侧的牵引线分别固定缠绕在位于两侧的内啮合齿轮315上，内啮合齿轮315被各自对应的棘轮314啮合后，中间轴312转动能够带动与棘轮314啮合的一侧的内啮合齿轮315转动，内啮合齿轮315转动从而拉动牵引线使夹耳22带动夹头21朝牵引绳连接在转动的内啮合齿轮315的方向移动，从而实现夹持装置2在透明帽1上的转动。The traction line is introduced into the handle 31 through the wire tube 32. The traction lines on both sides introduced into the handle 31 are fixedly wound around the internal gears 315 on both sides. After the internal gears 315 are engaged with their corresponding ratchets 314, the rotation of the intermediate shaft 312 can drive the internal gear 315 on the side engaged with the ratchet 314 to rotate. The rotation of the internal gear 315 pulls the traction line so that the clamping ear 22 drives the clamping head 21 to move in the direction where the traction rope is connected to the rotating internal gear 315, thereby realizing the rotation of the clamping device 2 on the transparent cap 1.
需要将夹持装置2向相反方向时，原理与上述拉动原理相同，仅需要医护人员通过旋钮312拉动中间轴朝向另一侧移动，此时位于另一侧的棘轮314与位于手柄壳体311内部的另一侧的内啮合齿轮315啮合，此时反方向转动中间轴313，从而使中间轴313带动棘轮314转动，从而带动另一侧的内啮合齿轮315转动，此时另一侧的内啮合齿轮315转动带动夹持装置2朝反方向移动。When the clamping device 2 needs to be moved in the opposite direction, the principle is the same as the above-mentioned pulling principle. The medical staff only needs to pull the intermediate shaft toward the other side through the knob 312. At this time, the ratchet 314 on the other side is engaged with the internal gear 315 on the other side of the handle shell 311. At this time, the intermediate shaft 313 is rotated in the opposite direction, so that the intermediate shaft 313 drives the ratchet 314 to rotate, thereby driving the internal gear 315 on the other side to rotate. At this time, the internal gear 315 on the other side rotates and drives the clamping device 2 to move in the opposite direction.
位于两侧的内啮合齿轮315的不同的转动方向均能够实现拉动夹持装置2朝向不同方向移动的效果，通过将牵引线在内啮合齿轮315上的缠绕的方向不同，就能够实现两侧的内啮合齿轮315朝不同方向转动均能够实现拉动牵引绳从而进一步实现拉动夹持装置的作用。The different rotation directions of the internal gears 315 on both sides can achieve the effect of pulling the clamping device 2 to move in different directions. By winding the traction line on the internal gear 315 in different directions, the internal gears 315 on both sides can rotate in different directions to pull the traction rope, thereby further achieving the function of pulling the clamping device.
上述技术方案中，采用向不同方向转动中间轴从而拉动牵引绳使夹持装置2移动是为方便医护人员对方向进行调整，使用起来更加符合习惯。In the above technical solution, the clamping device 2 is moved by rotating the intermediate shaft in different directions to pull the traction rope in order to facilitate the medical staff to adjust the direction, which is more in line with the habit of use.
牵引线的优选为尼龙绳，方便医生进行安装和消毒，且不易断裂。The traction line is preferably made of nylon rope, which is convenient for doctors to install and disinfect and is not easy to break.
透明帽1上在不设置夹持装置2上的时候，可以安装支撑套4，支撑套4在未使用状态下由依次连接的三层橡胶圈组成，由下至上分别为第一层橡胶圈41、第二层橡胶圈42、第三层橡胶圈43，第三层橡胶圈43上设有固定片431，第一层橡胶圈41内设有能够与固定片431配合的固定孔411，第三层橡胶圈43内设有支架44，支架44由环形分布在第三层橡胶圈43内的若干个独立支撑架组成，支架在未使用状态下的若干独立支撑架为收缩状态。When the clamping device 2 is not provided on the transparent cap 1, a support sleeve 4 can be installed. The support sleeve 4 is composed of three layers of rubber rings connected in sequence when not in use, namely, a first layer of rubber ring 41, a second layer of rubber ring 42, and a third layer of rubber ring 43 from bottom to top. A fixing piece 431 is provided on the third layer of rubber ring 43. A fixing hole 411 capable of cooperating with the fixing piece 431 is provided in the first layer of rubber ring 41. A bracket 44 is provided in the third layer of rubber ring 43. The bracket 44 is composed of several independent support frames distributed in an annular manner in the third layer of rubber ring 43. The several independent support frames of the bracket are in a retracted state when not in use.
在使用时首先将第一层橡胶圈41和第二层橡胶圈42穿过内圈11与外圈12的缝隙，由于内圈11与外圈12之间的缝隙并非一个完整圆，因此第一层橡胶圈41和第二层橡胶圈42上同样设有与外圈12的缺口对应的开口，将第二层橡胶圈42保留在内圈11与外圈12的缝隙内，第一层橡胶圈41穿过缝隙。During use, the first and second rubber rings 41, 42 are first passed through the gap between the inner and outer rings 11, 12. Since the gap between the inner and outer rings 11, 12 is not a complete circle, the first and second rubber rings 41, 42 are also provided with openings corresponding to the notches of the outer ring 12. The second rubber ring 42 is retained in the gap between the inner and outer rings 11, 12, while the first rubber ring 41 is passed through the gap.
向上翻折第一层橡胶圈41至外圈12外侧，再向下翻折第三层橡胶圈43，翻折到位后，将第三层橡胶圈43上的固定片431塞入到第一层橡胶圈41的固定孔411内，此时第三层橡胶圈43上的支架44打开，能够在手术中起到较好的支撑作用。Fold the first rubber ring 41 upward to the outside of the outer ring 12, and then fold the third rubber ring 43 downward. After folding it into place, insert the fixing piece 431 on the third rubber ring 43 into the fixing hole 411 of the first rubber ring 41. At this time, the bracket 44 on the third rubber ring 43 is opened, which can play a better supporting role during surgery.
透明帽1的内圈11内同样可以为手术器械的实用提供空间，通过透明帽1内圈11内的手术器械，并配合安装在外圈12的夹持装置2内的手术器械，能够极大提高了医护人员的同步操作性，同时多个器械配合工作能够给人员提高较好的视野以及操作的便捷性和准确性，减少了手术风险，并且夹持转装置在使用过程中即可进行转动，无需退出内窥镜和透明帽进行调整，能欧极大的方便医护人员在手术过程中对切换多个手术角度，减少器械的进出次数，提高安全性。The inner ring 11 of the transparent cap 1 can also provide space for the practical use of surgical instruments. The surgical instruments in the inner ring 11 of the transparent cap 1 and the surgical instruments in the clamping device 2 installed in the outer ring 12 can greatly improve the synchronous operability of medical staff. At the same time, the cooperation of multiple instruments can provide personnel with a better field of view and the convenience and accuracy of operation, reducing surgical risks. The clamping device can be rotated during use without the need to exit the endoscope and the transparent cap for adjustment, which can greatly facilitate medical staff to switch between multiple surgical angles during surgery, reduce the number of times the instrument is put in and out, and improve safety.
