Description

Technical Field

[0001] The present invention relates to the technical field of surgical medical devices, and particularly to a visible abortion suction tube. Background Art

[0002] The existing visible abortion suction tubes are mainly used for gynecological visual abortion surgeries, including a handle and a suction tube provided on the handle. The pipeline in the suction tube can aspirate gestational sac tissues to achieve an abortion surgery. The LED light-emitting diodes and micro-cameras at the head end of the suction tube can illuminate and perform real-time imaging on the interior of the uterine cavity to achieve a visual surgery.

[0003] In the prior art, the micro-camera is fixedly arranged at the head end of the suction tube, and the suction tube is of a rigid tube structure and is fixed on the handle, so that without moving and rotating the handle, the viewing angle observed by the camera is fixed and unchanged.

[0004] However, when aspirating gestational sac tissues, the suction tube often cannot move and rotate significantly, thus affecting the operator's operation experience. In addition, the endometrium is prone to bleeding, resulting in turbidity of the uterine fluid, causing the camera's field of view to be blurred, seriously affecting the operator's observation of the uterine cavity, prolonging the examination and surgery time, and increasing the patient's pain. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the defect of the existing visible abortion suction tube that the viewing angle of the camera cannot be adjusted without moving and rotating the handle during the surgery process, so as to provide a visible abortion suction tube that can be bent and rotated.

[0006] Another technical problem to be solved by the present invention is to overcome the defect that the camera's field of view is blurred in the existing visible abortion suction tube during the surgery process, so as to provide a visible abortion suction tube with an auxiliary water supply function.

[0007] To solve the above technical problems, the present invention provides a visible abortion suction tube, including: a handle and a suction tube provided on the handle, and a camera is provided at the head of the suction tube;

[0008] The suction tube is rotatably connected to the handle about an axis, at least part of the suction tube is a controllable swing section, and a steering member for controlling the swing angle of the controllable swing section is connected to the handle.

[0009] Optionally, a rotating sleeve is connected to the suction tube, and the rotating sleeve is rotatably and snap-connected to the handle.

[0010] Optionally, the rotating sleeve has an annular groove, and the handle has a limiting portion for extending into the annular groove.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0033] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0034] This embodiment provides a visible abortion suction tube, as Figure 1 、 Figure 2 shown, including: a handle 1 and a suction tube 2 provided on the handle 1. A camera 3 and a light-emitting member 4 are provided at the head of the suction tube 2. The tail of the suction tube 2 is rotatably connected to the handle 1 about an axis. Specifically, the camera 3 can be selected as a CMOS micro camera 3, and the light-emitting member 4 can have multiple ones, and is preferably an LED light-emitting diode. The cables of the camera 3 and the light-emitting member 4 pass through the suction tube 2 and the handle 1 in sequence, and then are connected to a cable plug 20, so as to realize the lighting and imaging functions.

[0035] As Figure 1 、 Figure 2 described, the visible abortion suction tube provided in this embodiment has three channels in the suction tube 2, namely a suction channel, a water supply channel and a cable channel. A suction hose is provided in the suction channel. A suction port 5 communicating with the suction hose is provided at the head of the suction tube 2. A suction joint 18 communicating with the suction hose is provided on the handle 1. A water supply hose is provided in the water supply channel. A water spray port 6 communicating with the water supply hose is provided at the head of the suction tube 2. A secondary water supply joint 19 communicating with the water supply hose is provided on the handle 1. A cable is provided in the cable channel. The CMOS micro camera 3 and several LED light-emitting diodes at the head of the suction tube 2 are respectively connected to the cable.

[0036] As Figure 1 shown, at least a part of the suction tube 2 is set as a controllable swing section 7. Specifically, the controllable swing section 7 is arranged at the part of the suction tube 2 close to the head. The controllable swing section 7 is preferably a snake bone assembly that can be controllably swung. When adjusting the angle of the snake bone assembly, the middle part of the suction tube 2 extending into the human body will not swing, avoiding the pain of the patient. As Figure 3 shown, the snake bone assembly is composed of multiple sections of snake bones, and each section is connected by a hinge. Soft steel wire ropes 8 are passed through the upper and lower holes of each section of snake bone. One end of the steel wire rope 8 is fixed to the end of the snake bone, and the other end leads to the handle 1; during operation, by pulling the two steel wire ropes 8, the swing angle of the snake bone assembly can be controlled. In addition, as a preferred embodiment, a hose made of rubber material is coated on the outer surface of the snake bone assembly, and is connected and sealed with the head end and the suction tube 2 through epoxy resin glue.

[0037] As Figure 1 、 Figure 4 shown, a rotating sleeve 9 is connected to the suction tube 2, and the rotating sleeve 9 is rotatably clamped to the handle 1 through a coaxial cylindrical structure. Specifically, the rotating sleeve 9 has an annular groove 10, and the handle 1 has a limiting portion 11 for extending into the annular groove 10. In addition, the rotating sleeve 9 has two symmetrically arranged limiting members 12 protruding radially, and the handle 1 has a limiting bump 13 cooperating with the limiting members 12, and the limiting bump 13 is located between the two limiting members 12; when the handle 1 is stationary, rotating the suction tube 2, the rotating sleeve 9 can drive the suction tube 2 to rotate accordingly. The limiting structures on the rotating sleeve 9 and the handle 1 enable the left and right steering angles of the suction tube 2 not to exceed 90°. In addition, in order to quickly know the position of the camera 3, a camera 3 position mark 14 is also provided on the rotating sleeve 9. The suction tube 2 and the rotating sleeve 9 can be integrally formed to improve the connection stability during the operation; in addition, the suction tube 2 and the rotating sleeve 9 can also be two parts processed separately and assembled together by clamping.

[0038] As Figure 5 shown, a steering member 15 for controlling the swing angle of the snake bone assembly is connected to the handle 1. The steering member 15 includes: a wire reel 16 and a steering wrench 17. The wire reel 16 is rotatably arranged on the handle 1 through a rotating shaft, and the steel wire rope 8 for adjusting the snake bone assembly is sleeved on the wire reel 16. The steering wrench 17 is connected to the wire reel 16, and the steering wrench 17 is arranged outside the handle 1 for controlling the swing angle of the wire reel 16. For example, when the steering wrench 17 is rotated forward, the wire reel 16 drives the steel wire rope 8 to be tightened upward, and the snake bone assembly bends upward; conversely, the snake bone assembly bends downward.

[0039] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
