Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and particularly relates to an endoscope biopsy forceps with adjustable multi-angles. Background Technique

[0002] The biopsy forceps is an irreplaceable tool for taking pathological specimens during endoscope examinations. There are various styles of biopsy forceps on the market at present. However, during the use of most biopsy forceps, the head end cannot be rotated independently. When it is necessary to rotate the head end for better tissue biopsy, the whole body often needs to be rotated. Therefore, during actual use, the efficiency is not high and the operation time is increased. For example, when dealing with parts such as the fundus of the stomach, the posterior wall of the gastric antrum, and the esophagus where the endoscope is difficult to reach precisely, due to the difficulty in controlling the bending of the end of the biopsy forceps, the use effect is not good.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0023] Please refer to Figures 1 to 5, the present utility model provides a technical solution: a multi-angle adjustable endoscopic biopsy forceps, including a handle assembly 1. An inner chute 101 is provided in the middle of the handle assembly 1. A rack buckle 102 is arranged above the handle assembly 1. A forceps movable traction block 2 is slidably connected to one side of the rack buckle 102, and a forceps rotating traction block 3 is slidably connected to the other side of the rack buckle 102. A clamping hole 301 is provided above the forceps rotating traction block 3, and a clamping edge 302 is arranged on the bottom surface of the clamping hole 301. The tooth-shaped opening of the rack buckle 102 faces downward, and one end of the rack buckle 102 close to the forceps rotating traction block 3 is suspended. When the forceps rotating traction block 3 is pushed towards the rack buckle 102, the rack buckle 102 is inserted into the clamping hole 301. When the rack buckle 102 is inserted into the clamping hole 301, the clamping edge 302 is embedded in the tooth shape to fix the position of the forceps rotating traction block 3. A transition connecting sleeve 4 is fixedly installed at the end of the handle assembly 1. A handle grip 103 is arranged at the end of the handle assembly 1 away from the transition connecting sleeve 4. A pair of symmetrical traction block handle rings 201 are arranged on the outer surface of the forceps movable traction block 2. The handle grip 103 and the traction block handle rings 201 are in the same plane. Through the handle grip 103 and the traction block handle rings 201, a doctor can operate the forceps movable traction block 2 to slide back and forth with one hand. One end of the transition connecting sleeve 4 is connected to a flexible sleeve 5. One end of the flexible sleeve 5 is connected to a front head bend 6. One end of the front head bend 6 is sleeved with a rotating cylinder 7. One end of the rotating cylinder 7 is rotatably connected to a forceps installation shaft 8. The rotating cylinder 7 is composed of an inner cylinder and an outer cylinder. The forceps installation shaft 8 is clamped between the inner cylinder and the outer cylinder with a transition fit. The forceps installation shaft 8 can rotate when stressed. A biopsy forceps assembly 9 is installed at the end of the forceps installation shaft 8. The biopsy forceps assembly 9 includes a forceps shaft 901. An upper forceps 902 and a lower forceps 903 are respectively hinged above and below the forceps shaft 901. A hinge chain 904 is hinged at the tails of the upper forceps 902 and the lower forceps 903. When a forceps movable traction rope 10 pulls the hinge chain 904, the upper forceps 902 and the lower forceps 903 are closed. A forceps movable traction rope 10 is arranged between the biopsy forceps assembly 9 and the forceps movable traction block 2. A forceps rotating traction rope 11 is arranged between the rotating cylinder 7 and the forceps rotating traction block 3. The forceps rotating traction rope 11 passes through one end of the flexible sleeve 5 from the inside to the outside and then is connected to the rotating cylinder 7 along the outer surface of the front head bend 6. When the forceps rotating traction rope 11 pulls the rotating cylinder 7, the front head bend 6 is stressed and bent, and when the front head bend 6 is not stressed, it returns to a straight state.

[0024] When in use, the doctor picks up the biopsy forceps with one hand through the handle assembly 1 and inserts two fingers into the traction block handle ring 201. Then, according to the situation, the doctor twists the forceps mounting shaft 8 with the other hand to change the angle of the biopsy forceps assembly 9. Since changing the angle of the biopsy forceps assembly 9 does not require rotating the handle assembly 1, the doctor's posture of operating the handle assembly 1 can be maintained in a comfortable state, so that tissue biopsy can be better performed and the efficiency can be improved. When the doctor slides the forceps movable traction block 2 by finger pressing, the upper forceps 902 and the lower forceps 903 are combined by pulling the articulated chain 904 through the forceps movable traction rope 10, thereby controlling the clamping of the biopsy forceps. When it is necessary to change the bending angle of the biopsy forceps assembly 9, the doctor slides the forceps rotating traction block 3 by hand. Sliding the forceps rotating traction block 3 can pull the front end of the front head bend 6 through the forceps rotating traction rope 11 to make the front head bend 6 bend, thereby changing the angle of the forceps. When the forceps rotating traction block 3 slides on the handle assembly 1, the rack buckle 102 is inserted into the clamping hole 301 and fixed in position by the clamping of the clamping edge 302 and the rack buckle 102 to maintain the bending angle of the front head bend 6. The front head bend 6 returns to a straight state when not under force after being bent by force.

[0025] In summary, a rotating cylinder 7 is provided between the forceps mounting shaft 8 for installing the forceps and the front head bend 6 of the multi-angle adjustable endoscopic biopsy forceps. The rotating cylinder 7 is in interference connection with the forceps mounting shaft 8. The forceps mounting shaft 8 can be twisted by hand to change the angle of the forceps. Since the head end can rotate independently, tissue biopsy can be better performed and the efficiency can be improved. A forceps rotating traction rope 11 is provided between the forceps rotating traction block 3 and the front end of the front head bend 6. Sliding the forceps rotating traction block 3 can pull the front end of the front head bend 6 through the forceps rotating traction rope 11 to make the front head bend 6 bend, thereby changing the angle of the forceps. When the forceps rotating traction block 3 slides on the handle assembly 1, the rack buckle 102 is inserted into the clamping hole 301 and fixed in position by the clamping of the clamping edge 302 and the rack buckle 102 to maintain the bending angle of the front head bend 6.
