Description

Technical Field

[0001] The utility model relates to the technical field of trocar flow regulation, in particular to a quick-detachable split flow regulating valve applied to trocars. Background Art

[0002] A trocar is a medical device consisting of a filler and a cannula. Its main function is to pass a needle through the skin and soft tissue to take tissue samples or inject drugs. It is simple, fast and safe to use, can reduce the pain and trauma of patients, and improve the accuracy and efficiency of diagnosis and treatment. The trocar has a wide range of uses and can be used in many fields such as clinical medicine, pathology, and imaging.

[0003] In order to facilitate flow adjustment, the trocars on the market need to be equipped with a flow regulating valve on the inlet pipe. The current flow regulating valve is fixed on the trocar and cannot be removed. For disposable trocars, they must be discarded as a whole after use, which leads to high costs and great waste. For non-disposable trocars, the subsequent cleaning and maintenance are also very troublesome. Utility Model Content

[0004] The technical problem to be solved by the utility model is that most of the current flow regulating valves are directly fixed on the puncture device and cannot be disassembled. For disposable puncture devices, they must be discarded as a whole after use, resulting in high costs and great waste. For non-disposable puncture devices, subsequent cleaning and maintenance are also very troublesome.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a quick-detachable split flow regulating valve used for a puncture device, comprising a main valve body, the main valve body comprising an arc-shaped first locking claw, an arc-shaped second locking claw, a first external control arm fixed to the outside of the arc-shaped first locking claw, a second external control arm fixed to the outside of the arc-shaped second locking claw and a bolt locking switch, and the arc-shaped first locking claw and the arc-shaped second locking claw are internally equipped with a split connecting pipe.

[0006] The first outer control arm and the second outer control arm are both provided with inner through holes matched with the bolt locking switch, and the outer ends of the first outer control arm and the second outer control arm are provided with lateral limit frames of an integral structure.

[0007] The bolt locking switch comprises an adjusting screw rod penetrating the inner through hole, a control handle fixed on the outer end of the adjusting screw rod and two locking nuts threadedly sleeved on the adjusting screw rod.

[0008] The outer walls on both sides of the split connecting pipe are provided with lateral assembly sets matched with the arc-shaped first locking claws and the arc-shaped second locking claws.

[0009] The arc-shaped first locking claw and the arc-shaped second locking claw are designed with a staggered layout.

[0010] An inner side limit slot matching with the locking nut is provided on the inner side surface of the lateral limit frame, and the locking nut is inserted into the inner side limit slot to be fixed with the lateral limit frame.

[0011] The beneficial effects of the utility model are:

[0012] (1) The utility model adopts a split structure design for a quick-detachable split flow regulating valve applied to a trocar, which can be quickly separated and easily replaced, thus greatly reducing the use cost;

[0013] (2) The entire regulating valve is adjusted by using a bolt locking switch. By rotating, the arc-shaped first locking claw and the arc-shaped second locking claw can be controlled to open and close, and the split connecting pipe can be controlled to be tightened and expanded, and the internal flux of the split connecting pipe can be freely adjusted;

[0014] (3) The arc-shaped first locking claw and the arc-shaped second locking claw are designed with a staggered layout, which can greatly increase the control stroke and facilitate opening and closing adjustment;

[0015] (4) By connecting the arc-shaped first locking claw, the arc-shaped second locking claw and the split connecting pipe, the fit of the three can be ensured without relying on the expansion and contraction of the split connecting pipe itself. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0018] Figure 2 It is a structural schematic diagram of a bolt locking switch in the utility model. DETAILED DESCRIPTION

[0019] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0020] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, 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 a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] Figure 1 and Figure 2 A quick-detachable split flow regulating valve used for a puncture device is shown, comprising a main valve body, the main valve body comprising an arcuate first locking claw 1, an arcuate second locking claw 2, a first external control arm 3 fixed to the outside of the arcuate first locking claw 1, a second external control arm 4 fixed to the outside of the arcuate second locking claw 2, and a bolt locking switch 5, and a split connecting pipe 6 is assembled inside the arcuate first locking claw 1 and the arcuate second locking claw 2.

[0022] One end of the split connecting tube 6 is sleeved on the feed tube of the trocar, and the other end is connected to the liquid inlet tube, and then the bolt locking switch 5 is rotated to squeeze the first external control arm 3 and the second external control arm 4, and control the spacing adjustment of the arc-shaped first locking claw 1 and the arc-shaped second locking claw 2, thereby controlling the internal flux of the split connecting tube 6.

[0023] The control principle is similar to that of a clamp.

[0024] For assembly purposes, the first outer control arm 3 and the second outer control arm 4 are provided with internal through holes that match the bolt locking switch 5 , and the outer ends of the first outer control arm 3 and the second outer control arm 4 have lateral limit frames 7 of an integral structure.

[0025] In order to cooperate with the screw adjustment, the bolt locking switch 5 includes an adjusting screw 51 passing through the internal through hole, a control handle 52 fixed to the outer end of the adjusting screw 51 and two locking nuts 53 threadedly sleeved on the adjusting screw 51.

[0026] The control handle 52 adjusts the gap between the two locking nuts 53 by controlling the adjustment screw 51 to rotate, thereby adjusting the distance between the first outer control arm 3 and the second outer control arm 4 .

[0027] In order to facilitate the connection of the set, the outer walls on both sides of the split connecting pipe 6 are provided with lateral assembly sets 8 that match the arc-shaped first locking claws 1 and the arc-shaped second locking claws 2.

[0028] The arc-shaped first locking claw 1 and the arc-shaped second locking claw 2 are inserted into the lateral assembly sleeve 8 and plugged into the split connecting pipe 6. When the distance between the arc-shaped first locking claw 1 and the arc-shaped second locking claw 2 becomes smaller, the split connecting pipe 6 can be clamped to reduce the flux inside the split connecting pipe 6; when the distance between the arc-shaped first locking claw 1 and the arc-shaped second locking claw 2 becomes larger, the split connecting pipe 6 can be expanded to increase the flux inside the split connecting pipe 6 and control the split connecting pipe 6 to reset.

[0029] In order to greatly reduce the clamping space, the arc-shaped first locking claw 1 and the arc-shaped second locking claw 2 are designed with a staggered layout.

[0030] In order to ensure the stability and limiting ability of the locking nut 53, an inner limiting slot matching the locking nut 53 is opened on the inner side of the lateral limiting frame 7, and the locking nut 53 is inserted into the inner limiting slot to be fixed with the lateral limiting frame 7.

[0031] When the control handle 52 drives the adjusting screw rod 51 to rotate, the locking nut 53 remains fixed, so that the distance between the first external control arm 3 and the second external control arm 4 can be adjusted, so that the flipping of the arc-shaped first locking claw 1 and the arc-shaped second locking claw 2 can be easily adjusted.

[0032] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
