Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to a surgical skin retractor. Background Art

[0002] Surgical retractors are the most commonly used instruments during surgery. During surgery, in order to reduce the patient's trauma and pain, doctors generally make smaller incisions on the surface of the human body, while the lesion is located deeper. Therefore, there are problems such as limited field of view of the surgical site and unclear anatomy. At this time, surgical retractors are often needed to retract the surgical incision for surgical operation. However, current retractors cannot adjust the retraction position when the wound is large, resulting in failure to fully retract the wound, affecting the surgical field of view.

[0003] The structure of the product can refer to a surgical retractor disclosed in Chinese patent document publication number: CN217366169U, including a retractor arm, one end of which is connected to a single-head retractor, and the other end is connected to a double-head retractor; the double-head retractor includes two "V"-shaped retractor rods, the converging ends of the two retractor rods are connected to the retractor arm, and the open ends of the two retractor rods are respectively connected to a hook body, and the hook body is a smooth arc.

[0004] In the above structure, the retraction position cannot be adjusted according to the size of the wound, resulting in the problem that it is inconvenient to insert the device when the wound is small, and it cannot be fully retracted when the wound is large.

[0005] Therefore, a surgical skin retractor that is convenient for adjusting the size of the retraction site is needed. Utility Model Content

[0031] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0032] Reference Figure 1-5A surgical skin retractor comprises: a handle 100, a connecting rod 101, a first hook body 102, and a second hook body 103. The connecting rod 101 is fixedly connected to one end of the handle 100, and the other end of the handle 100 is fixedly connected to a hook 104, so as to facilitate hanging the retractor. A sliding groove 105 is provided on the connecting rod 101, and a rack 106 is slidably connected in the sliding groove 105, and teeth are arranged on both sides of the rack 106. Gears 107 located on both sides of the rack 106 are rotatably connected to the connecting rod 101, and 107 is located in 105. The gear 107 is meshed with the rack 106. Two second hook bodies 103 are provided, which are respectively located on both sides of the first hook body 102, and one end of the two second hook bodies 103 is respectively fixedly connected to the gear 107. When the rack 106 slides, it drives the gear 107 to rotate, so that the two second hook bodies 103 are deflected, and the force position of the skin is adjusted.

[0033] The second hook body 103 includes: a connecting portion 108 fixedly connected to the gear 107 at one end and a hook head 109 hinged at the other end of the connecting portion 108, a hinge groove 110 is provided at one end of the connecting portion 108, a hinge pin 111 passing through the hinge groove 110 is provided on the connecting portion 108, and the hinge pin 111 passes through one end of the hook head 109, so that the hook head 109 is hinged to the connecting portion 108, so that the hook head 109 can deflect relative to the connecting portion 108.

[0034] A return spring 112 is disposed in the hinge slot 110, and both ends of the return spring 112 are fixedly connected to the hook head 109 and the inner wall of the hinge slot 110. When the skin is not retracted, when the second hook body 103 is close to the position of the first hook body 102, the second hook body 103 is flush with the first hook body 102.

[0035] The connecting rod 101 is provided with an open slot 113 communicating with the sliding slot 105, and the rack 106 is fixedly connected with a hinge shaft 114 passing through the open slot 113, and a push button 115 is hinged on the hinge shaft 114. The push button 115 is slidably connected to the connecting rod 101, and a hinge protrusion 116 is provided on the push button 115, and the hinge protrusion 116 is hinged to the hinge shaft 114, so that the push button 115 can deflect relative to the hinge shaft 114.

[0036] The connecting rod 101 is provided with a limit block 117 extending along both sides of the opening slot 113, and the push button 115 is provided with a limit protrusion 118, which is embedded between two adjacent limit blocks 117. When the limit protrusion 118 is embedded in the tooth groove of the limit block 117, the push button 115 is limited.

[0037] A compression spring 119 is connected between the push button 115 and the rack 106. A receiving groove 120 is provided on the push button 115. Two ends of the compression spring 119 are respectively connected to the push button 115 and the rack 106. One end of the compression spring 119 is inserted into the receiving groove 120. When the push button 115 is pressed, the compression spring 119 is compressed so that the limiting protrusion 118 does not fit into the tooth groove of the limiting block 117. When the push button 115 is not pressed, the limiting protrusion 118 fits into the tooth groove of the limiting block 117 under the action of the compression spring 119. Anti-slip grooves 121 are provided on the push button 115.

[0038] Working or installation process: When the wound is large, by pressing the push button 115, the limiting protrusion 118 is not embedded in the tooth groove of the limiting block 117, and the push button 115 is pushed to make the rack 106 slide, drive the two gears 107 to rotate, and make the two second hooks 103 deflect, adjust the retraction area, and when the push button 115 is no longer pressed, the limiting protrusion 118 is embedded in the tooth groove of the limiting block 117 to limit the rack 106. When retraction is performed, the second hook 103 contacts the skin, and the hook head 109 is deflected, so that the hook head 109 is always close to the skin. When in use, when the wound is small, the first hook 102 and the second hook 103 are located in a close position, which is convenient for the hook to be inserted. Under the action of the reset spring 112, the first hook 102 and the second hook 103 are flush.
