It discloses a disposable biopsy forceps, which includes an operating handle, a forceps body, a jaw, and a traction wire. One end of the forceps body is connected to the operating handle, and the other end is hinged to the jaw. One end of the traction wire is connected to the operating handle, and the other end is connected to the jaw after passing through the forceps. The jaw has a pair of jaws that are opened and closed by the traction wire, and the pair of jaws are staggered with scale lines along the extension direction of their length. The disposable biopsy forceps has a simple structure, which overcomes the problem that junior endoscopists and nurses cannot intuitively, quickly, and accurately judge the size of lesions when taking biopsies, and effectively shortens the endoscopic examination time.

[0004] It can be seen from the above application that the existing living body sampling forceps cannot quickly switch the clamp head clamp in the patient's body. When multiple sampling is required, the waiting time during the operation will be increased, and the endoscope will stay in the patient's body for too long, increasing the patient's discomfort and prone to complications. For this reason, a living body sampling forceps that can be quickly exchanged is proposed. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-Figure 5A quick-exchangeable biopsy forceps comprises: a handle body 10 and a spring tube protective tube 30, the handle body 10 is connected to the spring tube protective tube 30, a ring handle 40 is integrally formed at one end of the handle body 10 away from the spring tube protective tube 30, at least two ring handles 40 are provided, a push block 20 is slidably connected to the handle body 10, the number of the push blocks 20 is provided with two, a fixing block 11 is integrally formed on the outer wall of the handle body 10, a fixing groove 21 is provided on the inner wall of the outer ring of the push block 20, and the fixing block 11 can be buckled in the fixing groove 21, The two push blocks 20 are respectively connected to the first return spring 31 and the second return spring 32 in the handle body 10, a channel 301 is opened in the spring tube protection tube 30, and two channels 301 are provided. The first return spring 31 and the second return spring 32 respectively penetrate the two channels 301, and the end of the first return spring 31 away from the push block 20 is connected to the first sampling clamp head clamp 311, and the end of the second return spring 32 away from the push block 20 is connected to the second sampling clamp head clamp 321. The two push blocks 20 respectively control the first sampling clamp head clamp 311 and the second sampling clamp head clamp 321, and a limiting ring 12 is integrally formed on the handle body 10, and the surface of the push block 20 is provided with an anti-slip pattern, and the surface of the push block 20 is integrally formed with a push block ring 22, and a reset button 50 is inserted on the handle body 10. There are two reset buttons 50, which are respectively connected to the first return spring 31 and the second return spring 32 inside the handle body 10. Pressing the reset button 50 can extend the clamp head clamp in the retracted state, and the push block 20, The surfaces of the spring tube protective tube 30 and the reset button 50 are both divided into two colors for distinguishing the operation of the two clamps, and distinguishing the living samples clamped by the first sampling clamp 311 and the second sampling clamp 321. The spring tube protective tube 30 has a rounded corner at one end close to the clamp to facilitate smoother entry into the patient's body. The channel 301 has an opening at one end close to the clamp, which can accommodate the first sampling clamp 311 or the second sampling clamp 321, so as to facilitate the retraction of the clamp into the channel 301.

[0026] Structural principle:

[0027] like Figure 1-Figure 5 As shown, the first return spring 31 and the second return spring 32 are in a retracted state. Pressing the reset button 50 can extend the retracted clamp and enter the patient's body. Two push blocks 20 are used to respectively control the first return spring 31 and the second return spring 32. The first return spring 31 drives the first sampling clamp 311 alone, and the second return spring 32 drives the second sampling clamp 321 alone. When sampling, the two push blocks 20 of different colors are controlled to switch sampling.

[0028] In summary, the present invention can quickly exchange the living body sampling forceps, by arranging two push blocks 20, a reset spring, and a forceps head clamp on a handle body 10, and the two push blocks 20 respectively control the reset spring and the forceps head clamp, so that the forceps head clamp can be quickly switched after the living body sampling forceps penetrates into the patient's body; the waiting time during the operation is reduced, so that the doctor can perform the operation more efficiently, especially when multiple samplings are required, reducing the residence time of the endoscope in the patient's body, thereby reducing the patient's discomfort and possible complications.
