Description

TECHNICAL FIELD

[0001] The utility model relates to medical equipment technical field especially is involved in a rotatable suction stripping device. BACKGROUND

[0002] Suction stripping is a kind of medical instrument widely used in rhinology surgery, such as nasal septum deviation correction, endoscopic nasal cavity and sinus surgery, etc. The design of suction stripping enables doctors to perform tissue stripping and suction secretion simultaneously during surgery, which not only reduces the number of replacement of surgical instruments and shortens the operation time, but also greatly reduces the pain of patients.

[0003] In clinical surgery, suction stripping is often used to strip mucosa, cartilage membrane, etc., so its head end needs to be relatively sharp. In addition, the operator often needs to use a large force when holding the suction stripping, so an ergonomic handle is needed to facilitate the force and reduce the hand fatigue of the operator, so that the surgery is more efficient and safe. At the same time, it needs to be operated in multiple directions and angles conveniently in the actual use process to meet the operation requirements of the narrow space of nasal cavity. However, the tail end of the existing suction stripping is connected with suction skin tube, which cannot be freely rotated and adjusted in angle.

[0004] Therefore, it is urgent to develop a new suction stripping device that can rotate around the long axis. UTILITY MODEL CONTENTS

[0038] Example 1:

[0039] A rotatable suction peeling device includes a handle 1, a peeling head 2, a rotating connector 3, and a suction tube connector 4.

[0040] like Figures 1-2 As shown, the handle 1 in this embodiment has a side suction hole 11. The peeling head 2 is connected to the top end of the handle 1 and communicates with the interior of the handle 1. The head end of the peeling head 2 has a suction hole 21. The rotating connector 3 includes a female connector 31 and a male connector 32. The female connector 31 is connected to the tail end of the handle 1 and communicates with the interior of the handle 1, and the male connector 32 can be inserted into the female connector 31 and communicates with the interior of the female connector 31. A retaining ring 33 is provided between the female connector 31 and the male connector 32, and the female connector 31 can rotate around the male connector 32. The suction tube connector 4 is connected to the tail end of the male connector 32 and communicates with the interior of the male connector 32.

[0041] Example 2:

[0042] A rotatable suction dissection device includes a handle 1, a dissection head 2, a rotating connector 3, and a suction tube connector 4. The difference from Embodiment 1 is that the handle 1 in this embodiment has anti-slip texture 12 to increase friction and improve the stability of the surgical operation. The handle 1 is cylindrical with an outer diameter of 10-15 mm. The handle 1 has an arc-shaped groove 13 that conforms to the curve of the thumb for easy handling. A side suction hole 11 is located at the bottom center of the arc-shaped groove 13; by blocking the side suction hole 11 with the thumb, the suction hole 21 at the tip of the dissection head 2 can exert its suction function.

[0043] The dissecting head 2 in this embodiment has a flat and sharp tip with a slight arc-shaped bend to facilitate the dissection of the mucosa and perichondrium. The tail end of the suction tube connector 4 in this embodiment is connected to the negative pressure suction tube, and its tail end is provided with a multi-level anti-slip structure 41, which can effectively prevent the suction tube from falling off during operation.

[0044] Example 3:

[0045] A rotatable suction peeling device includes a handle 1, a peeling head 2, a rotating connector 3, and a suction tube connector 4. The difference from Embodiment 1 is that, as in... Figures 3-4As shown, in this embodiment, the female connector 31 has a first annular groove 311 on its circumferential inner wall, and the male connector 32 has a second annular groove 321 on its circumferential outer wall corresponding to the first annular groove 311. The retaining ring 33 is engaged between the first annular groove 311 and the second annular groove 321. The outer side of the female connector 31 has at least two through holes 312 at equal intervals. The through holes 312 are arranged radially and communicate with the first annular groove 311.

[0046] In this embodiment, the retaining ring 33 is a C-shaped retaining ring made of elastic material. When a pin or other component is used through the through hole 312, the retaining ring 33 can be fully pressed into the second annular groove 321 of the male connector 32, facilitating the disassembly of the male connector 32. When it is necessary to connect the male connector 32, simply place the retaining ring 33 onto the second annular groove 321 and insert it axially into the female connector 31. Since the retaining ring 33 is under a certain compression during insertion, when it extends into the first annular groove 311 of the female connector 31, it will expand appropriately, thus locking itself between the first and second annular grooves 311 and 321. A certain rotational clearance is maintained between the retaining ring 33 and the grooves, and between the inner wall of the female connector 31 and the outer wall of the male connector 32. At this time, due to the presence of the retaining ring 33, the female connector 31 can rotate around the male connector 32, while the male connector 32 remains stationary, thereby enabling the free rotation of the handle 1 connected to the female connector 31 during surgical operations. In this embodiment, the female connector 31 is provided with at least one set of sealing rings 34 on its circumferential inner wall. The sealing rings 34 are located between the handle 1 and the retaining ring 33, which can effectively prevent the leakage of the suction liquid.

[0047] Taking septoplasty as an example, the nasal septum mucosa on one side is first separated during the operation, with the suction port 21 of the dissecting head 2 facing the nasal septum bone and cartilage surface. When it is necessary to separate the nasal septum mucosa on the other side, the operation can be continued by rotating the female connector 31 180 degrees. The angle of use of the dissecting head 2 can be freely adjusted during the operation, without being restricted by the rigid material of the suction tube.

[0048] The above description of the embodiments is provided to enable those skilled in the art to understand and use the utility model. It will be apparent to those skilled in the art that various modifications can be easily made to these embodiments, and the general principles described herein can be applied to other embodiments without inventive effort. Therefore, the present utility model is not limited to the above embodiments, and any improvements and modifications made by those skilled in the art based on the disclosure of the present utility model without departing from its scope should be within the protection scope of the present utility model.
