Description

Technical Field

[0001] The utility model relates to the technical field related to intraoperative irrigation, in particular to a fine intraoperative irrigation piece. Background Art

[0002] At present, during general surgery in hospitals, the assistance of surgical assistants is very important. Currently, general surgical irrigation generally uses a surgical wound washer or a syringe, which requires frequent flushing with instruments and is not easy to control the water flow rate, making it inconvenient to use clinically. Especially in some emergency situations, if there is a delay, it will have an adverse impact on the surgery; because during intraoperative irrigation, the range of the target area to be irrigated is required to be relatively precise, and sometimes the range is relatively small. If the needle is too thick, the amount of medicine discharged is large, affecting the irrigation effect.

[0003] Therefore, we propose a fine intraoperative irrigation piece to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art, and to propose a fine intraoperative irrigation piece.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A fine intraoperative irrigation piece includes an infusion tube, a liquid pumping piece, and an irrigation head. The liquid pumping piece is set in a cylindrical shape, and the liquid pumping piece is fixedly connected and communicated with one end of the infusion tube. The liquid pumping piece includes a cylindrical shell. A lead-out tube communicating with the inside is arranged at the lower end of the cylindrical shell. The irrigation head adopts a needle structure without a tip and is sleeved on the lead-out tube. A limiting piece is arranged on the lead-out tube corresponding to the irrigation head. A piston is hermetically and slidably arranged in the cylindrical shell, and a control assembly for controlling the piston is arranged at the upper end of the cylindrical shell.

[0007] Preferably, the limiting piece includes clamping claws symmetrically arranged on both sides of the lead-out tube. Both clamping claws are rotatably connected to the lead-out tube, and an elastic limit is carried out between the clamping claws and the lead-out tube through a torsion spring.

[0008] Preferably, the irrigation head is set in a bent shape.

[0009] Preferably, an electric heater is clamped on the infusion tube.

[0010] Preferably, the control assembly is set as an electric telescopic rod.

[0011] Preferably, one-way valves are arranged at the connection positions of the lead-out tube and the infusion tube with the cylindrical shell.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: This device can be used for intraoperative irrigation operations. The irrigation fluid can be conveniently introduced through the infusion tube structure. The electric telescopic rod structure drives the piston to reciprocate, and at the same time, with the cooperation of two one-way valve structures, the ejection operation of the irrigation fluid can be realized; This device can be operated by hand, and the irrigation head at the liquid outlet adopts a needle-like structure, and the liquid outlet is relatively small, which can adapt to the irrigation operation of fine parts during the operation, and the irrigation head can be easily replaced, with high applicability; This device is also provided with a heating structure to further ensure the irrigation effect.

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0019] Referring to Figures 1-3 a kind of intraoperative fine irrigation part shown, including:

[0020] An infusion tube 1, a liquid pumping member 2 and an irrigation head 3. Among them, the liquid pumping member 2 is set in a cylindrical shape for convenient hand-holding. The liquid pumping member 2 is fixedly connected and communicated with one end of the infusion tube 1. Specifically, the liquid pumping member 2 includes a cylindrical housing 21. An outlet pipe 23 communicating with the inside is provided at the lower end of the cylindrical housing 21. This intraoperative fine irrigation part mainly realizes fine irrigation through the irrigation head 3. Among them, the irrigation head 3 adopts a non-pointed needle structure and is sleeved on the outlet pipe 23. The needle diameter of the irrigation head 3 is set to 10 - 20 millimeters and can be replaced according to requirements. Therefore, a limiting member is provided on the outlet pipe 23 corresponding to the irrigation head 3. The limiting member includes clamping claws 26 symmetrically arranged on both sides of the outlet pipe 23. Both clamping claws 26 are rotatably connected to the outlet pipe 23.
