Description

Technical Field

[0001] The present invention relates to the field of medical devices, and particularly to a novel multi-functional two-way grasping forceps for digestive endoscope nursing. Background Art

[0002] Digestive tract diseases are a series of diseases involving the digestive tract, including various disorders of the entire digestive system from the mouth to the anus. Common digestive tract diseases include: inflammatory diseases, ulcerative diseases, neoplastic diseases, functional diseases, as well as acute gastroenteritis and intestinal obstruction, etc.; Digestive endoscopes are important tools for the clinical diagnosis and treatment of digestive tract diseases. During the diagnosis and treatment process, digestive endoscopes usually need to be used in conjunction with a two-way grasping forceps for digestive endoscope nursing.

[0003] However, in the actual operation process, since medical staff need to control the endoscope and hold the two-way grasping forceps for digestive endoscope nursing with one hand, on the one hand, it will affect the convenient operation of medical staff, and on the other hand, it takes a long time for the two-way grasping forceps for digestive endoscope nursing to remove digestive tract foreign bodies from the digestive tract during use. Medical staff need to hold the two-way grasping forceps for a long time, and the arms of medical staff are prone to fatigue and soreness, which not only increases the physical strength consumed by medical staff during work, but also affects the normal progress of the operation.

[0004] And the two-way grasping forceps belong to medical devices that are frequently used. However, the two-way grasping forceps in the prior art have poor sealing performance, which will cause tissue or tissue fluid residues inside the two-way grasping forceps. And in order to ensure the clamping stability of the two-way grasping forceps, it is difficult to disassemble the two-way grasping forceps, and it is difficult to perform complete cleaning and disinfection on the two-way grasping forceps.

[0005] Therefore, the present invention discloses a novel multi-functional two-way grasping forceps for digestive endoscope nursing. Summary of the Invention

[0006] In order to solve the technical problems in the prior art that the two-way grasping forceps have complex operations, need to be held for a long time, increase the physical strength consumption of medical staff, and affect the convenient operation of medical staff, the present invention is realized through the following technical solutions:

[0007] A novel multi-functional two-way grasping forceps for digestive endoscope nursing, comprising: a sleeve, a driving sleeve, a push rod, and a chuck.

[0008] The push rod is sleeved inside the sleeve. The rear part of the sleeve is threadedly connected to the driving sleeve, and a cross groove is opened at the front end of the sleeve; card slots are arranged at the four corners of the cross groove.

[0009] A limiting rod is arranged at the rear part of the push rod. Limiting blocks are arranged in an array on the outer wall of the front part of the limiting rod and are connected to the sleeve. The rear end of the limiting rod is rotatably connected to the driving sleeve.

[0010] The front end of the push rod is provided with wedge-shaped blocks arranged in an array, and clamping blocks are arranged on the wedge-shaped blocks and are slidably connected to the chuck; by rotating the driving sleeve, the push rod is pushed forward and backward, driving the chuck to clamp or expand;

[0011] Furthermore, the outer wall of the rear part of the sleeve is threadedly connected to the driving sleeve, and the inner wall of the sleeve is provided with sliding grooves arranged in an array for installing limit blocks; the outer diameter of the sleeve ranges between 5 - 15 mm, and the length ranges between 30 - 150 cm;

[0012] Furthermore, clamping blocks are arranged on the inclined surfaces of the wedge-shaped blocks and are slidably connected to the chuck;

[0013] Furthermore, an inverted wedge-shaped block is arranged at the lower end of the chuck, and a locking groove is formed on the inclined surface of the inverted wedge-shaped block for slidably connecting a clamping head; friction lines for enhancing friction are arranged on the surface of the chuck;

[0014] Furthermore, grasping teeth are horizontally arranged at the upper ends of the two symmetrically arranged chucks.

[0015] The beneficial effects of the present invention are:

[0016] The present invention designs a new type of multifunctional two-way grasping forceps for digestive endoscope nursing, including: a sleeve, a driving sleeve, a push rod, and a chuck. The outer wall of the rear part of the sleeve is threadedly connected to the driving sleeve, the push rod is detachably installed inside the sleeve, a cross groove is opened at the front end of the sleeve for installing the chuck, and wedge-shaped blocks are arranged in an array at the front end of the push rod to connect the chuck;

[0017] During actual use, by rotating the driving sleeve, the push rod is pushed forward and backward. When the push rod moves forward, the forward-moving wedge-shaped block drives the chuck to expand outward. When the push rod moves backward, the backward-moving wedge-shaped block drives the chuck to contract. And when the chuck contracts and clamps, the threadedly connected sleeve and driving sleeve can ensure the stability of the clamping, and it is not necessary for medical staff to hold the two-way grasping forceps for a long time;

[0018] And the structure of the present invention is simple, and the connection methods are also simple sliding connection and threaded connection, which facilitate the quick disassembly and disinfection of the whole device, solving the problems in the prior art that the two-way grasping forceps are difficult to disassemble and it is difficult to carry out complete cleaning and disinfection of the two-way grasping forceps.
