微创手术是外科手术中的一种，通常是通过在病患身上做出一系列小口而完成外科手术，这种外科手术不需要很大的切口，这样有利于病患缩短恢复时间，同时利于病患减少不必要的身体伤害。Minimally invasive surgery is a type of surgery, usually by making a series of small incisions on the patient. Reduce unnecessary bodily harm to patients.

当微创手术中需要将体内切出的组织转移到体外时，例如将肿瘤组织、结石等切除物取出来的时候，需要采用取物袋或者样品回收袋伸入病患体内，将这些切除物收纳入取物袋或者样品回收袋中，然后随着取物袋或者样品回收袋移出到病患体外。When the tissue excised from the body needs to be transferred to the outside of the body in the minimally invasive surgery, for example, when the excised objects such as tumor tissue and stones are taken out, a collection bag or a sample recovery bag needs to be inserted into the patient's body, and these excised objects need to be inserted into the body of the patient. It is collected in a retrieval bag or sample recovery bag, and then removed from the patient's body along with the retrieval bag or sample recovery bag.

由于微创手术中的开口很小，现有的取物袋或者样品回收袋通常会卷起来装在支撑管内处于被束缚状态，然后通过病患身上的小口进入到病患体内，再在病患体内将袋完全打开，将切除的组织放入打开的袋中，通过拉绳扎紧袋口，然后通过拉绳以由病患身上开口处取出取物袋或者样品回收袋，完成切除物的取出工作。Due to the small opening in minimally invasive surgery, the existing collection bag or sample recovery bag is usually rolled up and placed in the support tube in a bound state, and then enters the patient's body through the small opening on the patient's body, and then enters the patient's body through the small opening on the patient's body. Completely open the bag inside the body, put the excised tissue into the open bag, tie the bag mouth with a drawstring, and then use the drawstring to take out the retrieval bag or sample recovery bag from the opening on the patient's body to complete the removal of the excision. Work.

这种类型的外科器械在本领域内是公知的，并且在Bell等的US546731、Kammerer等的US5480404、Tovey等的US5647372、Conlon等的US6383197、Horton的US20150297204和蔡信东的CN101366653A中都有记载。Surgical instruments of this type are well known in the art and are described in US546731 to Bell et al., US5480404 to Kammerer et al., US5647372 to Tovey et al., US6383197 to Conlon et al.

现有的外科器械需要外部套管用于束缚取物袋或者样品回收袋，也需要成对的弹性片用于使取物袋或者样品回收袋张开口，因此存在制作成本高的问题；另外，现有的此类外科器械都存在结构复杂的问题。Existing surgical instruments require an external sleeve for restraining the retrieval bag or the sample recovery bag, and also need pairs of elastic sheets for opening the retrieval bag or the sample recovery bag, so there is a problem of high manufacturing cost; Some of these surgical instruments have complex structures.

图4-1为本发明创造一种微创手术用的取物袋装置的结构示意图，此时支撑杆20为直杆，弹性部分21没有预弯曲；图4-2也是本发明创造一种微创手术用的取物袋装置的另一种结构示意图，此时支撑杆20为弧形杆，弹性部分21预弯曲出一定的幅度。Figure 4-1 is a schematic structural diagram of a retrieval bag device for minimally invasive surgery created by the present invention. At this time, thesupport rod 20 is a straight rod, and theelastic part 21 is not pre-bent; Figure 4-2 is also a microscopic device created by the present invention. Another structural schematic diagram of the retrieval bag device for invasive surgery, at this time, thesupport rod 20 is an arc rod, and theelastic part 21 is pre-bent to a certain extent.

图4-3展示了张口拉绳33与支撑杆20的弹性部分21末端部位连接的一种方式，图4-4展示了另外一种方式。二者的区别在于：张口拉绳33从收口圈111出来的方式不同，图4-3所示的张口拉绳33从收口圈111的另一端出来，不同于弹性部分21插入的那一端，这种方式得到的回收袋10的开口是呈半椭圆叶片状的，开口的幅度不是很大；而图4-4所示的张口拉绳33从收口圈111插入弹性部分的那一端出来，这种方式得到的回收袋10的开口是呈椭圆叶片状的，开口的幅度比较大。FIG. 4-3 shows one way of connecting theopening pulling cord 33 to the end portion of theelastic portion 21 of thesupport rod 20 , and FIG. 4-4 shows another way. The difference between the two is that the openingrope 33 comes out of theclosing ring 111 in different ways. The openingrope 33 shown in Fig. 4-3 comes out from the other end of theclosing ring 111, which is different from the end where theelastic part 21 is inserted. The opening of therecycling bag 10 obtained in this way is in the shape of a semi-elliptical blade, and the opening width is not very large; and theopening drawstring 33 shown in FIG. 4-4 comes out from the end where theclosing ring 111 is inserted into the elastic part. The opening of therecovery bag 10 obtained by the method is in the shape of an elliptical blade, and the opening width is relatively large.

图4-5显示了一种支撑杆20的弹性部分21结构示意图，在弹性部分21同一面上平行设置有若干过线孔211，这些过线孔用于穿过张口拉绳33。张口拉绳33一端连接在弹性部分21的端部，另一端穿过过线孔211后离开弹性部分21，使用时张口拉绳33与弹性部分21一起穿入回收袋10的收口圈111，同时使得张口拉绳33从该穿入部分的同侧收口圈111内引出来，并延伸到收口圈111外。当需要回收袋10的袋口11张开时，可以拉紧延伸到收口圈111外的那部分张口拉绳33，这样弹性部分21的端部受到偏向拉力，变得弯曲起来，从而使得套在弹性部分21的那部分收口圈111沿着弹性部分21的弯曲形状变形，而没有套在弹性部分21的那部分收口圈111呈现自然张开状态，这样使得整个收口圈111形成一个张开的口子，该张开的口子被手术操作人员用来装入病患被切除的组织。4-5 show a schematic structural diagram of theelastic part 21 of asupport rod 20 , a plurality of wire-passingholes 211 are arranged in parallel on the same surface of theelastic part 21 , and these wire-passing holes are used to pass through the openingdrawstring 33 . One end of the openingdrawstring 33 is connected to the end of theelastic part 21, and the other end passes through thewire hole 211 and then leaves theelastic part 21. When in use, the openingdrawstring 33 and theelastic part 21 pass through theclosing ring 111 of therecovery bag 10, and at the same time The openingdrawstring 33 is drawn out from the inside of theclosing ring 111 on the same side of the penetration part, and extends to the outside of theclosing ring 111 . When thebag opening 11 of therecovery bag 10 needs to be opened, the part of the openingdrawstring 33 extending outside theclosing ring 111 can be tightened, so that the end of theelastic part 21 is subjected to a biased pulling force and becomes bent, so that the elastic part is wrapped around the elastic part. The part of thecuff 111 at 21 deforms along the curved shape of theelastic part 21, while the part of thecuff 111 that is not sheathed on theelastic part 21 presents a natural open state, so that theentire cuff 111 forms an open mouth. The open port is used by the surgical operator to insert the removed tissue from the patient.

图4-6显示了本发明创造的另一种微创手术用的取物袋装置的结构示意图，该取物袋装置具有实施例5的结构，而且在刚性部分22的后部设置有作动杆50，所述作动杆50的第一端51与刚性部分22的后部铰接，作动杆50的第二端52上设置有容纳张口拉绳33的槽或孔；刚性部分22与作动杆50铰接部位附近设置有限位斜面。当不需要回收袋10开口时，作动杆50的第二端52与刚性部分22的末端贴合在一块；当需要回收袋10开口时，拨动作动杆50，使得作动杆50以第一端处的铰链轴为中心转动，作动杆50的第二端52与刚性部分22的末端远离。此种设置的优势在于：在病患体内打开回收袋10的袋口11时，不需要手术操作人员持续用力拉着张口拉绳33，而只需要将作动杆50沿着铰链轴转动超过90度，在弹性部分21弯曲的情况下，具有对张口拉绳33的反作用力，这个反作用力能够对作动杆50的第二端52进行压迫，使得作动杆50被压在限位斜面上，从而实现张口拉绳33在支撑杆20上的自锁，手术操作人员不需要再用力去维持回收袋10的张开了。4-6 are schematic diagrams showing the structure of another retrieval bag device for minimally invasive surgery created by the present invention. The retrieval bag device has the structure of Example 5, and an actuation is provided at the rear of therigid part 22Lever 50, thefirst end 51 of the actuatinglever 50 is hinged with the rear of therigid part 22, and thesecond end 52 of the actuatinglever 50 is provided with a slot or hole for accommodating theopening pulling rope 33; A limiting slope is provided near the hinged portion of the movingrod 50 . When therecovery bag 10 does not need to be opened, thesecond end 52 of the actuatingrod 50 is abutted with the end of therigid part 22; when therecovery bag 10 needs to be opened, the actuatingrod 50 is toggled so that the actuatingrod 50 moves at the first The hinge shaft at one end rotates around the center, and thesecond end 52 of the actuatingrod 50 is away from the end of therigid portion 22 . The advantage of this arrangement is that when opening thebag mouth 11 of therecovery bag 10 in the patient's body, the operator does not need to continuously pull the mouthopening pull cord 33 with force, but only needs to rotate theactuating lever 50 along the hinge axis by more than 90 degrees. When theelastic part 21 is bent, it has a reaction force to theopening pulling rope 33, and this reaction force can press thesecond end 52 of the actuatingrod 50, so that the actuatingrod 50 is pressed on the limiting slope. , so that the self-locking of theopening pulling rope 33 on thesupport rod 20 is realized, and the operator does not need to exert force to maintain the opening of therecovery bag 10 .

优选地，所述限位斜面的倾斜角α为60°-85°，倾斜角在这个范围内，则能尽量缩短作动杆50的长度，而且能让回收袋10的开口尽量大。Preferably, the inclination angle α of the limiting slope is 60°-85°, and within this range, the length of the actuatingrod 50 can be shortened as much as possible, and the opening of therecovery bag 10 can be made as large as possible.

弹性部分21可以为等截面杆，也可以为前部细小后部粗大的变截面杆。Theelastic part 21 can be a rod of constant section, or a rod of variable section with a small front part and a thick rear part.

弹性部分21的横截面为椭圆形或者长方形，以使得弯曲方向的刚性最小，这样使得弹性部分21处的弯曲方向可控制。The cross section of theelastic portion 21 is oval or rectangular, so as to minimize the rigidity in the bending direction, so that the bending direction at theelastic portion 21 can be controlled.

在本发明创造中，支撑杆20的弹性部分21由具有弹性的材料制作而成，例如采用钛合金、铝合金、镁合金、不锈钢、有机玻璃、橡胶或者碳纤维；所述支撑杆20的刚性部分22由相对廉价的、具有较高刚度的材料制作而成，例如聚酯塑料、木头、不锈钢、铝合金等材料。In the creation of the present invention, theelastic part 21 of thesupport rod 20 is made of elastic material, such as titanium alloy, aluminum alloy, magnesium alloy, stainless steel, plexiglass, rubber or carbon fiber; the rigid part of thesupport rod 20 22 is made of relatively inexpensive materials with high stiffness, such as polyester plastic, wood, stainless steel, aluminum alloy, etc.
