The instrument integrates multiple functions, is easy to operate and reliable in sealing, and remarkably improves the nursing efficiency and safety of the drainage tube.

Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to a scissors forceps for nursing drainage tube after gastrointestinal tumor surgery. BACKGROUND

[0002] After gastrointestinal tumor surgery, multiple drainage tubes must be used to drain the incision. In order to prevent the backflow of drainage fluid and the entry of air into the body cavity, it is often necessary to temporarily clamp the drainage tube during nursing. At present, ordinary vascular forceps or special drainage tube clamps are commonly used to complete this operation in clinical practice.

[0003] However, the prior art has the following disadvantages: Complicated operation: when using ordinary vascular forceps to clamp the soft tube, it is necessary to find a suitable clamping position, and the forceps are prone to slipping and are not fixed firmly.

[0004] Single function: special drainage tube clamps can usually only achieve the function of clamping. When it is necessary to simultaneously process the connection horn of the drainage tube or perform cutting and other operations, medical personnel need to replace other tools (such as scissors), which increases the operation steps and the risk of infection.

[0005] Poor compatibility: many drainage tubes have horn joint, and ordinary instruments are difficult to effectively seal the central hole of the horn while clamping the soft tube, which has the risk of not being sealed tightly.

[0006] Therefore, there is an urgent need for a multifunctional instrument that integrates clamping, fixing and sealing functions in one and is specifically used for nursing drainage tubes. SUMMARY

[0007] The purpose of the present application is to overcome the defects of the prior art and provide a medical multifunctional scissors forceps with ingenious structure, simple operation and multiple functions, which can reliably clamp the drainage soft tube, fix the horn and seal the central hole thereof at the same time.

[0008] To achieve the above-mentioned purpose, the present application adopts the following technical solutions: A scissors forceps for nursing drainage tube after gastrointestinal tumor surgery, comprising a scissors forceps body, the scissors forceps body comprising a handle, a forceps head and a connection between the handle and the forceps head; the key lies in that the connection is provided with a connecting rod perpendicular to the plane of the scissors forceps body, and the top end of the connecting rod is movably connected with a support plate through a ball hinge structure; The support plate is an obtuse-angled bent metal plate, comprising a terminal end connected with the ball hinge structure, an operation part at the top end and a clamping part at the bent part; the top end of the support plate is provided with a circular protrusion for closing the soft tube port, and the clamping part is an inwardly recessed arc structure for clamping and fixing the rod part of the surgical soft tube horn; The outer side of the connecting rod is sleeved with a spring, one end of the spring acts on the joint or the base of the connecting rod, and the other end is connected to the end of the supporting plate; under the tension of the spring, the supporting plate keeps the initial state of the open jaws under normal circumstances.

[0009] Further, the ball hinge structure includes a spherical supporting head arranged at the top end of the connecting rod and a bowl-shaped support matched with the spherical supporting head arranged at the end of the supporting plate.

[0010] Further, the inner side working surface of the jaw is provided with anti-skid lines or tooth grooves to enhance the stability of clamping.

[0011] Further, the end of the handle is provided with a finger ring for preventing slipping during use.

[0012] The working principle and beneficial effects of the present application are as follows: Function integration: the present application combines the clamping function of scissors with the dedicated drainage tube fixing and sealing device. The horn mouth rod part is clamped by the clamping part, the hose is clamped by the jaw, and the hose end is sealed by the circular protrusion. A single instrument can complete multiple operations, greatly improving the nursing efficiency.

[0013] Linkage sealing: the design cleverly uses the principle of lever. When the user holds the handle, the jaws are closed to clamp the hose, and the horn mouth slides under the clamping force, driving the rod part to press the supporting plate, so that the circular protrusion at the top end is automatically and accurately aligned and sealed to the hose end, realizing the linkage of clamping and sealing, and the operation is simple and reliable.

[0014] Self-adaptive adjustment: the supporting plate is connected to the connecting rod through the ball hinge structure, which has a certain activity freedom in multiple directions, can adaptively adjust the angle, and can adapt to different models and angles of the horn mouth and the hose to ensure the sealing effect.

[0015] Automatic reset: the spring structure ensures that the supporting plate can automatically return to the open state after the handle is released, which is convenient for the next use and placement. DETAILED DESCRIPTION

[0018] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0019] like Figures 1 to 4 As shown, the present invention provides a scissor forceps for postoperative drainage tube care in gastrointestinal tumor surgery. Its main body is a standard scissor-type forceps body, which consists of two components that are cross-hinged by a pivot, including a handle 1, a forceps head 2, and a connecting part 3.

[0020] At the pivot point of the joint 3, a connecting rod 4 perpendicular to the plane of the clamp body is fixedly installed. A spherical support head 51 is provided at the top of the connecting rod 4. A bent metal support plate 5 with an obtuse angle (e.g., 120°-150°) is movably connected to the spherical support head 51 through a bowl-shaped support at its end, forming a ball joint mechanism that allows the support plate 5 to swing at multiple angles.

[0021] The support plate 5 has an inwardly recessed arc-shaped locking part 53 at the bend, the shape of which matches the rod part 7 of a common drainage tube flare. The top of the support plate 5 has a smooth circular protrusion 52. A spring 6 is sleeved on the outside of the connecting rod 4, with its lower end abutting against the joint 3 and its upper end connected to the end of the support plate 5.

[0022] In the initial state (e.g.) Figure 4 Under the tension of spring 6, support plate 5 opens outward and maintains a certain distance from pliers head 2.

[0023] In use, medical staff hold handle 1 with one hand and first use the clamping part 53 on the support plate 5 to engage the rod part 7 of the drainage tube's flared end. Then, use the forceps 2 to clamp the tubing 8 at the rear end of the flared end, roughly aligning the end of the tubing 8 with the circular protrusion 52. At this point, slowly tighten handle 1, and the forceps 2 will close together to firmly clamp the tubing 8. Simultaneously, due to the clamping force of the forceps 2, the flared end is pressed and will slide slightly downwards along its slope, causing its rod part 7 to press down on the support plate 5, overcoming the elastic force of the spring 6 and rotating it towards the forceps 2. Finally, the circular protrusion 52 at the top of the support plate 5 moves and pushes into the end of the tubing 8, completely sealing it, thus achieving simultaneous clamping and sealing. After releasing the handle, under the action of the spring 6, all components return to their initial open state.

[0024] The above merely describes the preferred embodiments of the present application and is not used to limit the present application, and although the present application is described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or equivalently replace some technical features thereof. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
