Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a live sampling forceps that reduces damage to the bronchoscopy forceps channel. Background Technology

[0002] Disposable biopsy forceps are primarily used for endoscopic biopsy of tissues such as the stomach, intestines, bladder, and bronchi. They help doctors obtain samples of diseased tissue for pathological examination and analysis, thus aiding in the diagnosis and treatment of various diseases. Guided by a bronchoscope, the forceps pass through the bronchoscopic inner tubing to reach the trachea and bronchi, locating the area requiring biopsy. The doctor operates the handle to control the opening and closing of the forceps, pushing the slider to open the jaws and pulling the slider to close the jaws, thus grasping the target tissue. Current disposable biopsy forceps typically have a forceps head consisting of two opening and closing flaps made of medical-grade stainless steel, usually designed in a rounded cup shape. Although the forceps head is stamped and polished, the rounded cup shape, due to its lack of smoothness, can still wear down the narrow forceps channel, or even puncture, puncture, or pinch the bronchoscopic inner tubing.

[0003] This phenomenon often occurs at the bends in the bronchoscope forceps tubing. These bends conform to the natural curves and complex structure of the airway, allowing the bronchoscope to reach various parts of the trachea and bronchi. When inserting or removing the forceps, the friction generated by the forceps tip passing through these bends can easily damage the inner wall of the forceps channel. This not only affects the doctor's normal diagnostic and treatment procedures but also causes significant financial losses.

[0004] Polytetrafluoroethylene (PTFE) is a high-molecular polymer with excellent lubricity, formed by the addition polymerization of tetrafluoroethylene. It is currently the self-lubricating material with the lowest coefficient of friction. PTFE also possesses excellent chemical stability, biocompatibility, and high-temperature resistance, making it widely used in the medical field. It is used to manufacture cardiovascular stents, artificial joints, artificial urethras, soft tissue fillers, plastic surgery materials, and sutures. PTFE can reduce friction, minimize tissue damage, prevent tissue adhesion, and improve the biocompatibility and chemical stability of medical devices, making it an ideal coating material for medical devices. Therefore, leveraging the advantages of PTFE coatings, improvements can be made to bronchoscopic biopsy forceps to avoid damage to the inner wall of the forceps channel. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a live sampling forceps that reduces damage to the bronchoscopy forceps channel. It has the characteristics of simple structure, convenient use, and can reduce the frictional resistance between the forceps head and the inner wall of the forceps channel, thus avoiding damage to the forceps channel.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a live sampling forceps that reduces damage to the bronchoscopy forceps channel, including a sampling forceps pull ring handle, a slider, a spring wire reel, and a sampling forceps head controlled by a traction steel wire, and also includes a forceps head frame and symmetrically arranged openable and closable spherical forceps flaps inside it. The outer surfaces of the forceps head frame and the spherical forceps flaps are provided with a self-lubricating coating made of fluoroplastic material, and the spherical forceps flaps are spherical in shape when closed.

[0007] The aforementioned live sampling forceps for reducing damage to the bronchoscopy forceps channel has a self-lubricating coating made of polytetrafluoroethylene.

[0008] The aforementioned live sampling forceps for reducing bronchoscopic forceps injury includes a sampling forceps head with a Y-shaped traction head and a main rivet. Each spherical forceps flap has a central hole in its middle. The lower ends of the two spherical forceps flaps are riveted to the upper ends of the Y-shaped traction head. The forceps head frame is cylindrical with an upward-facing axial groove at its upper part. The two spherical forceps flaps enter the forceps head frame through the axial groove. The main rivet passes through the riveting holes on both sides of the forceps head frame and the central hole, positioning the two spherical forceps flaps within the forceps head frame. The lower end of the Y-shaped traction head is riveted to the upper end of the traction wire. The lower end of the forceps head frame is fixedly connected to the upper end of a spring wire drum. The lower end of the spring wire drum is fixedly connected to the upper end of a pull ring handle. The lower end of the traction wire passes through the spring wire drum and enters the central hole at the upper part of the pull ring handle, connecting with a slider that is slidably fitted in the middle of the pull ring handle.

[0009] The aforementioned live sampling forceps for reducing damage to the bronchoscopy forceps channel has length markings on the spring wire spool.

[0010] This utility model provides a live sampling forceps that reduces damage to the bronchoscopy forceps channel. It is equipped with a sampling forceps head including a sampling forceps pull ring handle, a slider, a spring wire reel, and a traction steel wire controlled by a sampling forceps head. It also includes a forceps head frame and symmetrically arranged openable and closable spherical forceps flaps inside. The outer surfaces of the forceps head frame and the spherical forceps flaps are coated with a self-lubricating coating made of fluoroplastic material. When the spherical forceps flaps are closed, they are in a spherical shape.

[0011] The beneficial technical effects of this utility model are as follows: 1. When the two spherical forceps are closed, they form a spherical shape, which reduces the sharpness and makes the shape smoother compared to the original round-headed cup-shaped sphere, thus reducing the frictional resistance between the forceps and the inner wall of the bronchoscope channel. 2. The self-lubricating coating improves the smoothness of the sampling forceps head, creating a slippage effect when the sampling forceps head contacts the inner wall of the bronchoscope channel, effectively preventing damage to the inner wall of the bronchoscope channel. 3. The spring wire reel has length markings, making it easy for the operator to judge the depth of insertion of the sampling forceps head into the bronchoscope channel, avoiding forced passage when reaching the bend of the channel. This utility model has a simple structure and is easy to use. The spherical forceps and self-lubricating coating reduce the frictional resistance when contacting the inner wall of the bronchoscope channel, avoiding medical device accidents and economic losses during use, and improving the efficiency of medical operations.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] like Figures 1-9 As shown, this utility model provides a biopsy forceps that reduces damage to the bronchoscopy forceps channel. Its usage is as follows: When the operator needs to obtain a biopsy sample from the patient, first, the outer flexible tube 4 of the bronchoscope is inserted into the patient's bronchus. Then, the sampling forceps head is inserted into the forceps channel 8 within the outer flexible tube 4. While inserting, the operator observes the length markings 10 on the spring wire reel 3 of the biopsy forceps. Based on the length markings 10, the operator determines when the sampling forceps head reaches the bend 5 of the forceps channel 8. The operation should be gentle, avoiding forced passage. Ideally, the bend 5 of the forceps channel 8 should be straightened until the sampling forceps head extends beyond its front end and reaches the biopsy area. The operator's index and middle fingers hold the slider 6, and the thumb pulls the pull ring handle 1, which drives the traction wire 7 to manipulate the spherical forceps flap 14 to open. Then, the thumb pushes the pull ring handle 1, which drives the traction wire 7 to manipulate the spherical forceps flap 14 to grasp the biopsy tissue sample. Finally, the biopsy forceps are pulled out to obtain the patient's biopsy tissue sample.
