Description

Wound bone surgery incision spreader

Technical Field

The invention relates to the technical field of surgical instruments, in particular to a wound orthopedic surgery incision spreader.

Background

Surgical incision spreaders are a common tool used in surgical procedures to hold open a patient incision.

With the development of medical science, the final goal of medical science is to make the operation more concise and convenient, and in the existing shell operation, the skin muscle is usually pulled to two sides by using an operation draw hook after the skin muscle is cut, so that the operation can be further carried out.

The traction surgical retractor is very labored due to the large contraction force of human muscle, and even in long-time surgery, medical personnel need to be replaced midway to draw the surgical retractor, so that the opening effect is achieved.

Therefore, the existing equipment lacks convenience and is inconvenient to use.

(II) technical scheme

In order to solve the problems, the invention provides a wound orthopedic surgery incision spreader, which comprises two handle assemblies, two spreading rods, a plurality of claw assemblies and a second rotating member;

the handle assembly is in a scissor shape, one end of the handle assembly is provided with a grip, and the other end of the handle assembly is a connecting end; the middle part of the handle component is provided with a first rotating part and an adjusting screw;

the two handle components are respectively arranged at two ends of the opening rod; the two opening rods are arranged in parallel, and two ends of each opening rod are respectively connected with the connecting end of one handle assembly; the end part of the opening rod is rotatably connected with the connecting end through a second rotating piece; the middle parts of the two handle components and the two opening rods form a closed loop structure;

the claw assembly comprises a fixing ring and a claw; the fixed ring is sleeved on the opening rod.

Preferably, the first rotating member is provided with a ratchet assembly.

Preferably, the fixing ring is provided with a limiting groove along the circumferential surface; and a limiting pin is arranged on the opening rod along the horizontal direction, and the limiting pin is inserted into the limiting groove in a matching manner to form a limiting mechanism.

In the invention, when the handle assembly is folded, the opening rod is expanded outwards to open the operation incision. The hook claw hooks two sides of the operation incision and moves along with the opening rod to open the operation incision, the fixing ring can move on the opening rod at will, and meanwhile the number of the hook claw can be selected according to the size of the operation incision. The adjusting screw is used for locking the first rotating member and controlling the rotating state of the first rotating member. The spreader bar can only be closed after the adjusting screw is loosened.

The invention can open the operation incision for a long time without consuming manpower, and has simple structure and convenient use.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings in conjunction with the following detailed description. It should be understood that the description is intended to be exemplary only, and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

As shown in fig. 1-2, the wound orthopedic surgery incision spreader provided by the invention comprises two handle assemblies 1, two spreading rods 2, a plurality of hook claw assemblies 3 and a second rotating member 6;

the handle assembly 1 is in a scissor shape, one end of the handle assembly 1 is provided with a grip 11, and the other end of the handle assembly 1 is provided with a connecting end 12; the middle part of the handle component 1 is provided with a first rotating piece 4 and an adjusting screw 5;

the two handle assemblies 1 are respectively arranged at two ends of the opening rod 2; the two opening rods 2 are arranged in parallel, and two ends of each opening rod 2 are respectively connected with the connecting end 12 of one handle assembly 1; the end of the opening rod 2 is rotatably connected to the connecting end 12 via a second rotating member 6; the middle parts of the two handle components 1 and the two opening rods 2 form a closed loop structure;

the finger assembly 3 includes a fixing ring 31 and a finger 32; the fixing ring 31 is fitted over the spreader bar 2.

In the invention, when the handle assembly 1 is folded, the opening rod 2 expands outwards to open the operation incision. The hook claws 32 hook both sides of the operation incision and move along with the opening rod 2 to open the operation incision, and the fixing ring 31 can move freely on the opening rod 2, and meanwhile, the number of the hook claws 32 can be selected according to the size of the operation incision.

The adjusting screw 5 is used for locking the first rotating member 4 and controlling the rotating state of the first rotating member 4. The opening bar 2 can only be closed after the adjusting screw 5 is loosened.

In an alternative embodiment, the first rotating member 4 is provided with a ratchet assembly. The ratchet assembly is used to control the handle assembly 1 to remain closed to inhibit closure of the spreader lever 2.

In an alternative embodiment, the fixing ring 31 is provided with a limiting groove 33 along the circumference; set up spacer pin 7 along the horizontal direction on the pole 2 of strutting, in spacer pin 7 cooperation inserted spacing groove 33, formed stop gear, prevent that solid fixed ring 31 from removing along the axis.

It should be noted that the hook component 3 which is not used can rotate to the other side (the side far away from the operation incision) along the circumferential surface, so as to avoid influencing the operation sight; the claw component 3 to be used rotates to the position of the limit pin 7 to work normally. The limiting pin 7 has good positioning and limiting effects on the hook component 3, and prevents the hook component 3 from moving.

In summary, the handle assembly 1 controls the opening and closing movement of the opening rod 2, so as to achieve the purpose of opening the surgical incision for a long time without consuming manpower. When the operation is completed, the spreader bar 2 is closed after the adjusting screw 5 is loosened.

It is to be understood that the above-described embodiments of the present invention are merely illustrative of or explaining the principles of the invention and are not to be construed as limiting the invention. Therefore, any modification, equivalent replacement, improvement and the like made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention. Further, it is intended that the appended claims cover all such variations and modifications as fall within the scope and boundaries of the appended claims or the equivalents of such scope and boundaries.
