Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical devices, specifically a pathological composite sampling scissors. Background Technology
[0002] When pathologists collect or process specimens, they often need to cut open the lumen for observation or sampling. When the lesion is located in a small lumen or the structure of the lesion is fragile, the combination of traditional steel probes and ordinary medical scissors often leads to difficulties in operation, inaccurate cutting positions, or even damage to the lumen and lesion structure, making it impossible to correctly determine the degree of lesion and the sampling location.
[0003] Furthermore, when pathologists use scissors to cut open lumens or other tissues, they often need to interrupt the cutting process if they encounter abnormal calcified tissue or small anastomoses. They then need to remove the anastomoses with scissors or other instruments, or directly cut open the abnormal calcified tissue or even the anastomoses. These operations are either time-consuming and laborious, and interrupt the sampling process, resulting in inconsistent incision surfaces, or they significantly affect the sharpness of the scissors, leading to unsatisfactory results in future use and shortening the lifespan of the instruments. Utility Model Content
[0004] The purpose of this invention is to provide a pathological composite sampling scissor that avoids the need for frequent alternation between medical scissors and steel probes in existing pathological sampling processes. Furthermore, it has a simple structure, is easy to operate, and has a good sampling effect.
[0005] The objective of this utility model is achieved through the following technical solution:
[0006] A pathological composite sampling scissors includes two scissor arms, which are hinged together at the middle. The front inner side of the scissor arms is provided with a blade, and the rear end of the scissor arms is provided with a finger ring. The characteristic feature is that a probe assembly is provided on the front side of one of the scissor arms, and the rear end of the probe assembly is connected to a drive assembly for driving the probe assembly to swing left and right.
[0007] Compared with the prior art, the advantages of this utility model are:
[0008] 1. By setting up a drive component and a probe component on the front side of the scissor arm, the phenomenon of pathology staff frequently alternating between medical scissors and steel probes in traditional sample collection is avoided, thus improving work efficiency. In addition, the control wire in the drive component pulls several connecting blocks to rotate around the corresponding hinge axis, thereby driving the flexible probe sleeve to swing left and right, improving the convenience of operation.
[0009] 2. By setting a blade reinforcement section, the strength of the scissor blade is improved, avoiding damage to the blade when cutting hard tissue, and further improving the service life of the scissors. In addition, by setting an extension handle, the lever arm of the force applied during cutting is extended, achieving the effect of cutting hard tissue with less effort. Attached Figure Description

[0014] The present invention will now be described in detail with reference to the accompanying drawings and embodiments:
[0015] like Figure 1-3 The image shown is a schematic diagram of an embodiment of a pathological composite sampling scissors provided by this utility model:
[0016] A pathological composite sampling scissors includes two scissor arms 1, which are hinged together at the middle. The front inner side of the scissor arm 1 is provided with a blade 2, and the rear end of the scissor arm 1 is provided with a finger ring 3. The characteristic is that a probe assembly 4 is provided on the front side of one of the scissor arms 1, and the rear end of the probe assembly 4 is connected to a driving assembly 5 for driving the probe assembly 4 to swing left and right.
[0017] Preferably, the front end of the scissor arm 1 has a pointed tip, and the front section of the scissor arm 1 gradually widens from front to back.
[0018] The probe assembly 4 includes a number of connecting blocks 41 that are hinged together in sequence, a fixing seat 42, and a flexible probe sleeve 43 that is sleeved on the outside of the connecting blocks 41. The fixing seat 42 is fixed on the outer wall of the front end of the scissor arm 1. The connecting blocks 41 are hinged together by hinge shafts extending vertically. The connecting block 41 at the rear end is also hinged to the fixing seat 42 by hinge shafts extending vertically.
[0019] The drive assembly 5 includes two control wires 51 and two rings 52. The two control wires 51 pass through the fixed base 42 and the remaining connecting blocks 41 except for the frontmost connecting block 41 in sequence, and the two control wires 51 are located on the left and right sides of each hinge axis respectively.
[0020] The front end of the control wire 51 is connected to the rear side of the frontmost connecting block 41, and the two rings 52 are respectively fixed to the rear ends of the two control wires 51.
[0021] The drive assembly 5 also includes a guide seat 53 fixed to the outer side of the front section of the scissor arm 1. The guide seat 53 is provided with a guide hole for the control wire 51 to pass through, and the control wire 51 slides in cooperation with the guide hole.
[0022] The flexible probe sleeve 43 is made of propylene-based material or rubber material.
[0023] Preferably, in this embodiment, the flexible probe sleeve 43 is made of propylene-based material (propylene-based material is also known as propylene-based elastomer or PBE, which is a high-performance polymer material with good transparency, easy processing, flexibility and elasticity).
[0024] Specifically, before cutting the tissue, the pathologist pulls the control thread 51 by the two rings 52 in the drive assembly 5, thereby causing several connecting blocks 41 in the probe assembly 4 to swing left and right around the corresponding hinge axis. Since the flexible probe sleeve 43 is made of acrylic-based material, when the connecting blocks 41 swing left and right around the corresponding hinge axis, the outer flexible probe sleeve 43 adapts to the movement of the connecting blocks 41, thereby realizing the left and right swing of the flexible probe sleeve 43. The pathologist uses the flexible probe sleeve 43 to first probe the inside of the lumen, thereby gaining a general understanding of the structure, direction, presence, size, and texture of the lumen, which is beneficial for cutting.
[0025] Each of the scissor arms 1 has a blade edge reinforcement 6 on its blade edge 2. The thickness of the blade edge reinforcement 6 is greater than the maximum thickness of the blade edge 2. The blade edge reinforcement 6 is located at the end of the blade edge 2 near the hinge point of the scissor arm 1.
[0026] The blade reinforcement 6 is preferably made of the same material as the scissor arm 1. It is designed to cut open hard tissues such as abnormal calcification, ossification, and anastomotic staples. It is dedicated to this purpose and is located at one end near the hinge point of the scissor arm 1. It has a shorter lever arm, thereby reducing instrument wear caused by cutting hard tissues. It further reduces damage to normal tissue structures or personnel injuries caused by improper operation when using worn-out blunt scissors to cut tissue samples. In specific situations such as frozen section sampling, it can effectively shorten the sampling time and the waiting time for intraoperative freezing.
[0027] Each scissor arm 1 has an extension handle 7 extending rearward from its inner rear end, and the central axis of the extension handle 7 forms an angle α with the extension line of its corresponding blade 2, the angle α being 8° to 15°.
[0028] Preferably, the included angle α is 10°.
[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
