Description

Recovery device applied to endoscopic surgery

[ technical field ] A method for producing a semiconductor device

The utility model relates to the technical field of medical equipment, in particular to a tissue and foreign matter recovery device for an endoscope.

[ background of the invention ]

The objects to be removed from the digestive tract of the human body can be divided into two categories, i.e., foreign bodies and excised autologous tissues. Common foreign substances are: batteries, coins, physician implanted prostheses, stones, etc. that the patient has mistakenly swallowed. Common autologous tissue that has been resected, primarily tissue resected by mucosal resection, submucosal dissection, and other endoscopic techniques, is often polyps and early stage tumors. Clinically, the meaning of taking out foreign bodies through an endoscope is mainly treatment, and the excised autologous tissues are taken out through the endoscope to obtain complete specimens in time so as to perfect pathological examination. Therefore, it is very important to remove these solid objects endoscopically.

Although there are multiple methods in widespread use, including fine foreign body forceps, wire baskets, disposable baskets, etc. However, there are significant disadvantages. For example, the foreign body forceps can only hold soft and small objects, and when the foreign body forceps face objects with large volume or smooth surfaces, the foreign body forceps need to take a long time for accurate holding, and the foreign body forceps often fall off during the taking process, and even cannot be finished by the method. The metal wire basket is fixed first both ends along the axial with 3 ~ 5 silk, and although durable, the target object is easily left out to the basket, often needs to try repeatedly, spends a lot of time, so is used for the practicality of retrieving to be limited. In addition, some autologous tissues can form floating objects after falling off and cannot be captured by foreign body forceps or a metal basket.

[ detailed description ] embodiments

In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following embodiments.

As shown in fig. 1 to 3, the utility model discloses a recovery device for endoscopic surgery, which comprises a hose 1 with an inner channel 11, an outer sheath tube 2, a first guide wire 3, a first control handle 4, a second guide wire 5, a second control handle 6, a net bag 7 and a closed bag 8.

The sheath tube 2 is connected with one end of the hose 1, a first chute 21 and a second chute 22 are arranged on the sheath tube 2, the first chute 21 and the second chute 22 are respectively communicated with the hose 1, the first control handle 4 is provided with a first slide block 41 capable of sliding in the first chute 21 and a push handle 42 extending out of the first chute 21 for hand operation, one end of the first guide wire 3 is fixed on the first slide block 41, the other end of the first guide wire 3 is provided with a first opening 31, the first guide wire 3 can be made of memory alloy, the first opening 31 is opened in a normal state, when the first slide block 41 drives the first guide wire 3 to move towards one end far away from the hose 1, the first guide wire 3 gradually extends into the hose 1 to be compressed, when the first guide wire 3 is driven by the first slide block 41 to move towards one end of the hose 1, the first guide wire 3 extends out of the hose 1 and automatically opens the first opening 31, the first opening 31 of the first guide wire 3 is matched with the net bag 7, the connection between the net bag 7 and the first opening 31 can adopt an integrated structure or a detachable structure, the detachable structure comprises threaded connection, interference connection, clamping connection, sleeving connection and the like, the integrated structure can directly fix and form the net bag 7 on the first opening 31, and the net bag 7 can be made of metal materials or other deformable soft materials; the second control handle 6 is provided with a second sliding block 61 capable of sliding in the second chute 22 and a second push handle 62 extending out of the second chute 22 for hand operation, one end of the second guide wire 5 is fixed on the second sliding block 61, the other end of the second guide wire 5 is provided with a second opening 52, the second guide wire 5 can be made of memory alloy, the second opening 52 is opened in a normal state, when the second sliding block 61 drives the second guide wire 5 to move towards one end far away from the hose 1, the second guide wire 5 gradually extends into the hose 1 to be compressed, when the second sliding block 61 drives the second guide wire 5 to move towards one end of the hose 1, the second guide wire 5 extends out of the hose 1 and automatically opens the second opening 52, the second opening 52 of the second guide wire 5 is matched with the sealing bag 8, the connection between the sealing bag 8 and the second opening 52 can adopt an integrated structure or a detachable structure, the detachable structure includes threaded connection, interference fit connection, joint, cup joint etc. and the integral type structure can be with airtight bag 8 directly fixed shaping 52 on the second opening, airtight bag 8 adopts for the soft plastics material harmless to the human body.
