Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a clamp for processing biological membranes for repairing uterine cavity. Background Art

[0002] Endometrial problems are common diseases in obstetrics and gynecology. They include intrauterine adhesions, endometriosis, etc. The commonly used treatment method in clinical practice is hysteroscopic surgery. Generally speaking, membranous adhesions or fibromuscular adhesions can be separated or surgically removed under hysteroscopy. Combined with hormone therapy and other means, the postoperative recurrence rate is about 3.1% to 23.5%, among which the rate of re-adhesion of severe intrauterine adhesions in the intrauterine cavity after treatment is as high as 50%. Nuoyimaier Medical Technology Co., Ltd. independently develops and produces endometrial repair membranes, which can promote the growth of epithelial cells in the functional layer of the endometrium, aiming to safely, efficiently and simply treat gynecological diseases such as endometrium. The method of use is: after hysteroscopic surgery, the ERM membrane spreads to cover the entire uterine cavity, forming a physical barrier in the uterine cavity to prevent the recurrence of adhesions, and can also promote the repair of the endometrial functional layer and basal layer through the membrane, accelerating the regeneration of damaged endometrium, so as to achieve the purpose of treatment. In order to ensure that the ERM membrane is smoothly unfolded after being delivered into the uterine cavity, the ERM membrane needs to be processed into bags. The currently available processing clamps cannot clamp the ERM membrane into a bag structure of corresponding size, and most of the clamp heads of the existing processing clamps are fixed, which cannot be used to process ERM membranes of uterine cavities of different sizes. Additional processing clamps need to be designed for processing, which has great limitations in use. Summary of the invention

[0003] The purpose of the present invention is to propose a biomembrane processing clamp for uterine cavity repair, in view of the fact that the processing clamps in the prior art are difficult to process the ERM membrane into a specific shape, resulting in the membrane-like uterine repair products being unable to act in the uterine cavity environment.

[0004] The technical solution of the present invention is: a uterine cavity repair biofilm processing clamp, comprising two clamp arms hinged to each other; the rear end of the clamp arm is provided with a gripping part, and the front end is provided with a clamping part; the clamping part is in a trapezoidal frame shape.

[0005] One of the clamping parts is open.

[0006] The other clamping part is in a closed trapezoidal shape and has a supporting arm in the middle thereof; the supporting arm is an extension of the clamp arm and is fixedly connected to the middle of the upper bottom edge and the lower bottom edge on the trapezoidal frame.

[0007] The area enclosed by the clamping part is adjustable. The clamping part comprises a lower clamping arm, an upper clamping arm and two retractable side clamping arms; the lower clamping arm is fixedly connected to the clamp arm; the two ends of the side clamping arm are respectively hinged with connecting sleeves; the connecting sleeves at the two ends of the side clamping arm are respectively slidably connected to the upper clamping arm and the lower clamping arm in a lockable manner.

[0008] A support member consisting of two guide rods which are lockably and slidably connected is fixed to the middle of the upper clamping arm and the middle of the lower clamping arm.

[0009] The holding portion is a holding hole.

[0010] The opposite surfaces of the tail ends of the two clamp arms are provided with locking teeth which can mesh with each other.

[0011] The side clamping arm is divided into two sections; the two sections are slidably connected in the form of a sleeve rod.

[0012] Rack parts are arranged on both sides of both ends of the lower clamp arm and the upper clamp arm along the length direction; elastic protrusions which can be locked with the rack parts of the upper clamp arm and the lower clamp arm are arranged on both sides of the interior of the connecting sleeve.

[0013] The support members at the middle of the upper clamping arm and the middle of the lower clamping arm are locked by screws.

[0014] By adopting the above technical scheme, the present invention has the following beneficial effects: (1) The clamping part of the uterine cavity repair biofilm processing clamp of the present invention is arranged in a trapezoidal shape, and the area enclosed by the clamping part is adjustable. The size of the clamping part area can be adjusted according to needs to adapt to the processing of biofilms of different sizes, thereby being able to adapt to surgery on patients with uterine cavities of different sizes, and having strong applicability.

[0015] (2) The clamping portion of the present invention is composed of a lower clamping arm, an upper clamping arm and two side clamping arms, and the connecting sleeves at both ends of the side clamping arms are respectively slidably connected to the upper clamping arm and the lower clamping arm in a lockable manner. The position of the side clamping arm can be adjusted by adjusting the position of the connecting sleeve on the upper clamping arm and the lower clamping arm, thereby adjusting the area of ​​the clamping portion, and the adjustment is very convenient.

[0016] (3) The side clamping arm of the present invention is retractable, and the area of ​​the clamping portion can be adjusted while keeping the distance between the upper clamping arm and the clamping arm unchanged.

[0017] (4) A support member consisting of two guide rods that are slidably connected and lockable is fixed to the middle of the upper clamping arm and the middle of the lower clamping arm of the present invention to ensure that when the area of ​​the clamping portion is adjusted, the entire clamping portion remains in a relatively stable state, thereby facilitating stable clamping.

[0018] (5) The gripping portion of the present invention adopts a gripping hole, which not only saves materials but also increases gripping stability.

[0019] (6) The opposite surfaces of the rear end of the clamp arm of the present invention are provided with locking teeth that can mesh with each other, which can always keep the processing clamp in a clamping state without the need for continuous manual force, thereby reducing the burden on medical staff.

[0020] (7) The side clamp arm of the present invention is divided into two sections; the two sections are slidably connected by a sleeve rod, which not only has a simple structure but also makes the movement between the two sections of the side clamp arm smoother.

[0021] (8) The connecting sleeve of the present invention is locked with the rack portion by means of an elastic protrusion, so that the position of the connecting sleeve can be adjusted at any time, making the adjustment more convenient.
