Embodiment 1

[0042] like Figure 1-Figure 13 As shown, a rotatable thermal biopsy forceps with a water injection tube includes a clamp head structure 1, a connecting structure 2, a clamp head control structure 3, an electrode plug 4 and a transmission wire 5 connecting the electrode plug 4 and the clamp head structure 1; The clamp control structure 3 includes a core rod 301, a slip ring 302 slidingly connected to the outside of the core rod 301, and a spray pipe assembly. The spray pipe assembly has a water injection port 6, a spray port 7 facing the clamp head structure 1, and a connection between the water injection port 6 and The liquid channel 8 of the spray port 7; the two ends of the connecting structure 2 are respectively connected to the clamp head structure 1 and the core rod 301 in rotation. The other end of the clamp 101 and the spray pipe assembly is fixedly connected with the slip ring 302 so that the slip ring 302 drives the spray pipe assembly to rotate or reciprocate axiall...

Embodiment 2

[0054] In Embodiment 1, the transmission wire 5 and the electrode interface 3022 are not directly connected to the spray pipe assembly, so it is necessary to reserve another place to install the transmission wire 5 and the electrode interface 3022, which will cause the structure of the present invention to be too complicated and easy to produce structural interference. For this reason, this embodiment is improved as follows: one end of the transmission wire 5 is fixedly connected with the spray pipe 3031, the other end of the transmission wire 5 is connected with the slip ring 302, the slip ring 302 is provided with an electrode interface 3022, and an electrode is installed in the electrode interface 3022 seat 3023, the transmission wire 5 passes through the electrode seat 3023, and the electrode plug 4 is inserted into the electrode seat 3023 to abut against the transmission wire 5 (such as Figure 8 shown).

[0055] The electrode plug 4 is pressed tightly on the transmissio...

Embodiment 3

[0058] On the basis of the second embodiment, since the transmission wire 5 has a smaller diameter and lower strength, it is necessary to add a reinforcement structure outside the transmission wire 5 to connect with the moving parts. Specifically, the water injection pipe 3033 is sleeved on the transmission wire 5 The outer peripheral tee 13 is formed, and the end of the tee 13 close to the inner tube 3032 along the axial direction of the transmission wire 5 is connected with the booster tube 17 located at the outer periphery of the transmission wire 5; One end of the ring 302 is connected with the riveted pipe 18 located on the outer periphery of the drive wire 5 ; the booster pipe 17 is connected with the inner pipe 3032 , and the riveted pipe 18 is connected with the slip ring 302 .

[0059] like Figure 8 and Figure 13 As shown, the tee 13 has outlets in three directions: front, rear, and down. The booster tube 17 is welded or bonded to the inner wall of the front port o...

Abstract

The invention discloses rotatable hot biopsy forceps with a water injection pipe. The hot biopsy forceps comprise a forceps head structure, a connecting structure, a forceps head control structure, an electrode plug and a transmission wire for connecting the electrode plug with the forceps head structure, wherein the forceps head control structure comprises a core rod, a sliding ring connected to the outer part of the core rod in a sliding mode and a spraying pipe assembly; the spraying pipe assembly is provided with a water injection opening, a spraying opening facing the direction of the forceps head structure and a liquid channel communicating the water injection opening with the spraying opening; and two ends of the connecting structure are rotationally connected with the forceps head structure and the core rod correspondingly, the forceps head structure comprises a forceps clip which is connected with one end of the spraying pipe assembly and driven by the spraying pipe assembly to be clamped or closed, and the other end of the spraying pipe assembly is fixedly connected with the sliding ring, so that the slip ring drives the spraying pipe assembly to rotate or axially reciprocate. Synchronous movement of the spraying opening and the forceps head structure can be guaranteed, and tissue can be conveniently clamped in time after hemostasis.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a rotatable thermal biopsy forceps with a water injection tube. Background technique [0002] Thermal biopsy forceps connect the biopsy forceps with the electrode equipment, so that the forceps head is energized to perform electrical cutting on cell tissue, the cutting process is fast and the bleeding is less. The thermal biopsy forceps in the prior art have the following defects: (1) The thermal biopsy forceps does not have its own water injection pipe or the water injection pipe and the forceps head cannot realize synchronous control, and the cell tissue cannot be clamped in time after the water injection pipe is flushed with water Tissues cannot be accurately clamped when the amount of bleeding is large and fast. (2) When the clamp head rotates, the outer tube also rotates synchronously. When in use, the outer tube is placed in the channel of the endoscope, and th...
