技术领域Technical Field
本发明涉及医疗器械技术领域，具体涉及一种周向可旋转水路结构及能量医疗设备。The present invention relates to the technical field of medical devices, and in particular to a circumferentially rotatable water channel structure and energy medical equipment.
背景技术Background Art
能量医疗器械(例如高频电刀、电凝钩和电凝手术钳)主要用于电外科手术中的组织切割和血管或组织闭合密封的手术场景中；能量医疗器械在进行电外科手术的过程中，能量医疗器械的末端执行器通过有效电极尖端产生的高频高压电流与机体接触时对组织进行加热，实现对肌体组织的分离和凝固。在对一处肌体组织进行手术后，末端执行器的温度较高，容易导致组织热损伤以及粘连现象，为了有效的对末端执行器进行有效降温，通常在能量医疗器械内设置有用于向末端执行器循环输送冷却液的水路结构，但受到现有水路结构的限制，使得末端执行器在手术的过程中不易进行周向转动调节，限制了能量医疗器械的手术使用的灵活性。Energy medical devices (such as high-frequency electrosurgery, electrocoagulation hooks and electrocoagulation surgical forceps) are mainly used in surgical scenarios of tissue cutting and blood vessel or tissue closure and sealing during electrosurgery. During electrosurgery, the end effector of the energy medical device heats the tissue when it contacts the body through the high-frequency and high-voltage current generated by the effective electrode tip, thereby achieving separation and coagulation of body tissue. After surgery on a body tissue, the temperature of the end effector is high, which can easily lead to thermal damage and adhesion of the tissue. In order to effectively cool the end effector, a water channel structure for circulating coolant to the end effector is usually provided in the energy medical device. However, due to the limitations of the existing water channel structure, it is not easy to adjust the end effector's circumferential rotation during surgery, which limits the flexibility of the surgical use of the energy medical device.

A rigid water outlet pipe 61 and a flexible water outlet pipe 62 are sequentially arranged between the water outlet end of the cooling chamber 41 and the external cold source, and a circulation loop for the circulation of the cooling medium is formed between the cooling chamber 41 and the external cold source in cooperation with the rigid water inlet pipe 51 and the flexible water inlet pipe 52. The cooling medium circulates the heat of the heating part of the end effector 4 to continuously transfer it to the external cold source, which not only eliminates the risk of thermal damage to the tissue and adhesion caused by the high temperature of the heating surface of the end effector 4, but also improves the efficiency of heat dissipation and cooling. At the same time, the middle part of the soft water outlet pipe 62 is fixed in the handle shell 1 through the installation part 63, and the part of the soft water outlet pipe 62 located between the fixed connection between the soft water outlet pipe 62 and the handle shell 1 and the connection between the soft water outlet pipe 62 and the rigid water outlet pipe 61 is set as the second extension part 621, so that the two ends of the second extension part 621 along the length direction of the second extension part 621 are respectively restricted by the fixed connection between the soft water outlet pipe 62 and the handle shell 1 and the connection between the soft water outlet pipe 62 and the rigid water outlet pipe 61, and the second extension part 621 has an expansion stroke amount for switching from the initial state to the second state; so that when the hand wheel 2 is rotated to drive the end When the actuator 4 rotates forward together, the second extension portion 621 will be regularly and gradually stretched out for corresponding adaptation under the action of restrictions at both ends; and when the handwheel 2 is rotated to drive the end actuator 4 to rotate reversely together, the second extension portion 621 will be regularly and gradually squeezed, bent and bent for corresponding adaptation under the action of restrictions at both ends; effectively avoiding interference and restriction on the circumferential rotation adjustment of the end actuator 4, achieving effective cooling of the end actuator 4 while ensuring the flexibility of the circumferential rotation adjustment of the end actuator 4, and improving the surgical flexibility of the energy medical equipment equipped with the water channel structure of this embodiment. By connecting the middle parts of the soft water outlet pipe 62 and the soft water inlet pipe 52 into one body through the mounting portion 63, on the one hand, it is convenient to fix the middle parts of the soft water outlet pipe 62 and the soft water inlet pipe 52 in the handle shell 1, thereby simplifying the assembly process; on the other hand, it is possible to make the fixed connection between the first extension portion 521 and the handle shell 1 and the fixed connection between the second extension portion 621 and the handle shell 1 basically located at the same position along the axial direction, so that the stretching and expanding rules and the squeezing and bending rules of the first extension portion 521 and the second extension portion 621 are basically consistent, thereby ensuring the stability of the water channel structure in use of this embodiment.
具体应用中，所述安装部63上对应软性出水管62和软性进水管52的位置均沿轴向贯穿形成有穿孔；在进行装配时，分别将软性出水管62和软性进水管52穿过对应的穿孔直至安装部63位于软性出水管62和软性进水管52的设定位置后，再通过向穿孔内填充胶水进行固定；整个装配过程操作方便。In a specific application, the positions of the mounting portion 63 corresponding to the flexible water outlet pipe 62 and the flexible water inlet pipe 52 are axially penetrated with perforations; during assembly, the flexible water outlet pipe 62 and the flexible water inlet pipe 52 are respectively passed through the corresponding perforations until the mounting portion 63 is located at the set positions of the flexible water outlet pipe 62 and the flexible water inlet pipe 52, and then fixed by filling glue into the perforations; the entire assembly process is easy to operate.
具体应用中，所述能量医疗设备可选为高频电刀、电凝钩或电凝手术钳中的一种；当能量医疗设备设置为高频电刀时，末端执行器4为电刀部；当能量医疗设备为电凝钩时，末端执行器4为电钩头；末端执行器4为电凝手术钳时，末端执行器4为钳头。In specific applications, the energy medical device can be selected as one of a high-frequency electric knife, an electric coagulation hook or an electric coagulation surgical forceps; when the energy medical device is set as a high-frequency electric knife, the end effector 4 is the electric knife part; when the energy medical device is an electric coagulation hook, the end effector 4 is the electric hook head; when the end effector 4 is an electric coagulation surgical forceps, the end effector 4 is the forceps head.
需要说明的是，因为在旋转手轮2带动末端执行器4一起正向转动时，第一伸展部521和第二伸展部621均有规律地逐渐被拉展开；以及在旋转手轮2带动末端执行器4一起反向转动时，第一伸展部521和第二伸展部621均有规律地逐渐被挤压绕折弯曲；所以可以确保第一伸展部521和第二伸展部621在经过长时间且多次的被拉展开和被挤压绕折弯曲后仍不会出现相互缠绕的问题，确保使用的稳定性和使用寿命。It should be noted that, when the rotating hand wheel 2 drives the end effector 4 to rotate forward, the first extension portion 521 and the second extension portion 621 are gradually stretched out in a regular manner; and when the rotating hand wheel 2 drives the end effector 4 to rotate reversely, the first extension portion 521 and the second extension portion 621 are gradually squeezed, folded and bent in a regular manner; therefore, it can be ensured that the first extension portion 521 and the second extension portion 621 will not be entangled with each other after being stretched out and squeezed, folded and bent for a long time and many times, thereby ensuring the stability of use and service life.
需要说明的是，所述软性进水管52的进水端和所述软性出水管62的出水端均延伸至所述手柄壳1外并与外部冷源连通。It should be noted that the water inlet end of the flexible water inlet pipe 52 and the water outlet end of the flexible water outlet pipe 62 both extend to the outside of the handle housing 1 and are connected to an external cold source.
如图2至图6所示，可选地，所述软性进水管52沿水平方向的投影与所述软性出水管62相重叠；所述刚性进水管51沿水平方向的投影与所述刚性出水管61相重叠。这样设置，可以使得第一伸展部521与刚性进水管51的连接处以及第二伸展部621与刚性出水管61的连接处基本位于沿轴向的同一位置，更好地确保第一伸展部521和第二伸展部621的被拉展开规律以及第一伸展部521和第二伸展部621的被挤压绕折弯曲规律基本保持一致，提升本实施例的水路结构使用稳定性。As shown in Fig. 2 to Fig. 6, optionally, the projection of the flexible water inlet pipe 52 along the horizontal direction overlaps with the flexible water outlet pipe 62; the projection of the rigid water inlet pipe 51 along the horizontal direction overlaps with the rigid water outlet pipe 61. This arrangement can make the connection between the first extension part 521 and the rigid water inlet pipe 51 and the connection between the second extension part 621 and the rigid water outlet pipe 61 basically located at the same position along the axial direction, better ensuring that the stretching law of the first extension part 521 and the second extension part 621 and the squeezing, twisting and bending law of the first extension part 521 and the second extension part 621 are basically consistent, thereby improving the use stability of the waterway structure of this embodiment.
如图3至图5以及图8和图9所示，可选地，所述连接管3位于所述手柄壳1内的部分的外侧设置有凸圆部31，所述手柄壳1内沿水平方向设置有连接部7，所述连接部7内沿轴向贯穿有安装孔，所述凸圆部31转动连接在所述安装孔内；所述连接部7沿竖向朝向所述软性进水管52的上端面设置为二级台阶71，所述二级台阶71的转角处进行圆弧平滑过渡。在将第一伸展部521和第二伸展部621随手轮2正向转动逐渐被拉展开的过程中，二级台阶71为第一伸展部521和第二伸展部621的中部下端提供一个支撑点，使得第一伸展部521和第二伸展部621有规律地逐渐被拉展开进行对应的适配；并且连接部7沿水平方向布置在手柄壳1内，连接部7与手柄壳1的内壁之间没有明显的间隙并且二级台阶71上没有明显的间隙，确保第一伸展部521和第二伸展部621被拉展开或被挤压绕折弯曲的过程中不会被卡住。还通过将二级台阶71的转角处进行圆弧平滑过渡，减少第一伸展部521和第二伸展部621与二级台阶71进行接触时产生的摩擦力，避免第一伸展部521和第二伸展部621在逐渐被拉展开的过程中产生损伤。同时通过凸圆部31与安装孔的转动连接关系提高连接管3沿周向转动的稳定性。As shown in Figures 3 to 5 and Figures 8 and 9, optionally, a convex portion 31 is provided on the outer side of the portion of the connecting tube 3 located in the handle shell 1, and a connecting portion 7 is provided in the handle shell 1 along the horizontal direction, and a mounting hole is axially penetrated in the connecting portion 7, and the convex portion 31 is rotatably connected in the mounting hole; the connecting portion 7 is provided with a secondary step 71 along the vertical direction toward the upper end face of the soft water inlet pipe 52, and the corners of the secondary step 71 are smoothly transitioned in an arc. In the process of gradually pulling and unfolding the first extension part 521 and the second extension part 621 with the positive rotation of the hand wheel 2, the secondary step 71 provides a support point for the middle lower end of the first extension part 521 and the second extension part 621, so that the first extension part 521 and the second extension part 621 are gradually pulled and unfolded regularly for corresponding adaptation; and the connecting part 7 is arranged in the handle shell 1 along the horizontal direction, and there is no obvious gap between the connecting part 7 and the inner wall of the handle shell 1 and there is no obvious gap on the secondary step 71, ensuring that the first extension part 521 and the second extension part 621 will not be stuck in the process of being pulled and unfolded or squeezed and bent. The corner of the secondary step 71 is also smoothly transitioned into an arc to reduce the friction generated when the first extension part 521 and the second extension part 621 contact the secondary step 71, thereby avoiding damage to the first extension part 521 and the second extension part 621 in the process of being gradually pulled and unfolded. At the same time, the rotational connection relationship between the convex part 31 and the mounting hole improves the stability of the connecting pipe 3 in the circumferential rotation.
如图3至图5所示，可选地，所述手轮2沿轴向朝向所述凸圆部31的端面设置有定位部21；所述连接部7内设置有腔体，所述安装孔与所述腔体连通，所述腔体的沿水平方向的一内壁对应所述定位部21凸设有第一限位部72和第二限位部73，所述第一限位部72和所述第二限位部73沿所述手轮2的周向间隔布置，且所述定位部21沿所述手轮2的周向位于所述第一限位部72和所述第二限位部73之间。通过第一限位部72对手轮2正向转动的最大角度位置进行限制，且通过第二限位部73对手轮2反向转动的最大角度位置进行限制，使得在手轮2正向转动至定位部21与抵接第一限位部72的位置(即第一伸展部521和第二伸展部621处于第二状态的位置)后，无法接着正向转动，且使得在手轮2反向转动至定位部21抵接第二限位部73的位置(即第一伸展部521和第二伸展部621处于初始状态的位置)后，无法接着反向转动；确保在手轮2带动末端执行器4在设定的角度范围内转动的基础上不损坏第一伸展部521和第二伸展部621。As shown in Figures 3 to 5, optionally, a positioning portion 21 is provided on the end face of the handwheel 2 axially facing the convex portion 31; a cavity is provided in the connecting portion 7, the mounting hole is connected to the cavity, and a first limiting portion 72 and a second limiting portion 73 are convexly provided on an inner wall along the horizontal direction of the cavity corresponding to the positioning portion 21, the first limiting portion 72 and the second limiting portion 73 are arranged at intervals along the circumference of the handwheel 2, and the positioning portion 21 is located between the first limiting portion 72 and the second limiting portion 73 along the circumference of the handwheel 2. The maximum angular position of the forward rotation of the hand wheel 2 is limited by the first limit portion 72, and the maximum angular position of the reverse rotation of the hand wheel 2 is limited by the second limit portion 73, so that after the hand wheel 2 is forwardly rotated to the position where the positioning portion 21 abuts the first limit portion 72 (i.e., the position where the first extension portion 521 and the second extension portion 621 are in the second state), it cannot continue to rotate forward, and after the hand wheel 2 is reversely rotated to the position where the positioning portion 21 abuts the second limit portion 73 (i.e., the position where the first extension portion 521 and the second extension portion 621 are in the initial state), it cannot continue to rotate reversely; ensuring that the first extension portion 521 and the second extension portion 621 are not damaged on the basis that the hand wheel 2 drives the end effector 4 to rotate within the set angle range.
具体地，在本实施例中，手轮2可以带动末端执行器4周向转动180°；当然了此处仅是对手轮2可以带动末端执行器4周向转动的角度范围的一种优选，不对其进行具体的限定，在其它实施例中，可以将该角度范围设置为90°、120°或270°等。Specifically, in this embodiment, the hand wheel 2 can drive the end effector 4 to rotate 180° in a circumferential direction; of course, this is only a preferred embodiment of the angle range within which the hand wheel 2 can drive the end effector 4 to rotate in a circumferential direction, and no specific limitation is imposed on it. In other embodiments, the angle range can be set to 90°, 120° or 270°, etc.
具体应用中，可以根据手轮2实际需要带动末端执行器4周向转动的角度范围值调整软性进水管52与安装部63的连接处至软性进水管52的出水端的长度进行对应的适配，即以安装部63作为测量基准，测量安装部63至软性进水管52的出水端的距离，并根据测量的距离值判断安装部63设置在软性进水管52上的位置是否满足末端执行器4周向转动的角度范围值的要求，整个装配过程更加简单。In specific applications, the length from the connection between the soft water inlet pipe 52 and the mounting part 63 to the water outlet end of the soft water inlet pipe 52 can be adjusted to adapt accordingly according to the actual need of the hand wheel 2 to drive the end effector 4 to rotate circumferentially. That is, the mounting part 63 is used as a measurement reference, the distance from the mounting part 63 to the water outlet end of the soft water inlet pipe 52 is measured, and based on the measured distance value, it is judged whether the position of the mounting part 63 on the soft water inlet pipe 52 meets the requirement of the circumferential rotation angle range of the end effector 4, and the whole assembly process is simpler.
如图4和图5所示，可选地，所述第一限位部72和第二限位部73将所述腔体沿轴向分隔成第一腔74和第二腔75，所述第一腔74位于所述第二腔75背离所述末端执行器4的一侧；所述凸圆部31转动连接在所述第一腔74内；所述手轮2对应所述第二腔75的位置的外壁上凸设有连接圆部22，所述连接圆部22转动连接在所述第二腔75内。通过连接圆部22与第二腔75的转动连接关系提高手轮2沿周向转动的稳定性，更加平稳的带动连接管3、末端执行器4、刚性进水管51和刚性出水管61沿周向转动，从而更加稳定地使得第一伸展部521和第二伸展部621有规律地逐渐被拉展开或有规律地逐渐被挤压绕折弯曲。As shown in Fig. 4 and Fig. 5, optionally, the first limiting portion 72 and the second limiting portion 73 divide the cavity into a first cavity 74 and a second cavity 75 along the axial direction, wherein the first cavity 74 is located on the side of the second cavity 75 away from the end effector 4; the convex circular portion 31 is rotatably connected in the first cavity 74; a connecting circular portion 22 is convexly provided on the outer wall of the hand wheel 2 corresponding to the position of the second cavity 75, and the connecting circular portion 22 is rotatably connected in the second cavity 75. The rotatable connection relationship between the connecting circular portion 22 and the second cavity 75 improves the stability of the circumferential rotation of the hand wheel 2, and more stably drives the connecting pipe 3, the end effector 4, the rigid water inlet pipe 51 and the rigid water outlet pipe 61 to rotate in the circumferential direction, so that the first extension portion 521 and the second extension portion 621 are gradually stretched or gradually squeezed and bent in a regular manner.

The conductive spring sheet 93 is always in contact with the outer peripheral surface of the conductive rod 81 to conduct electricity during the axial reciprocating movement of the conductive rod 81, thereby ensuring that the high-frequency current is directed to the end effector 4 during surgery. At the same time, it can also prevent the conductive wire 91 from being pulled during the axial reciprocating movement of the conductive rod 81, thereby extending the service life of the conductive wire 91.
