This medical animal experimental retractor of the present invention can achieve multi-dimensional adjustment of the pull hook position, easily adapting to experimental requirements and is easy to operate.

[0004] However, while existing medical animal retractors can retract the soft tissue of animals, they cannot automatically adjust the retraction force according to the retraction needs during the retraction process. This can lead to problems such as secondary wound damage due to excessive retraction force or insufficient retraction force, which may not ensure adequate exposure of the surgical field.

[0005] To address the problems raised in the background art, those skilled in the art have proposed a medical animal experiment spreader. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model provides a medical animal experimental retractor to solve the problems in the prior art where the retracting force cannot be automatically adjusted according to the retracting needs during the retracting process, which can easily cause secondary damage to the wound due to excessive retracting force when retracting the soft tissue of the animal, or fail to ensure sufficient exposure of the surgical field due to insufficient retracting force.

[0007] A medical animal experimental spreader includes an operating unit and a spreading unit. The operating unit includes an operating handle, inside which a lithium battery and a telescopic rod are installed. A tension sensor is fixedly connected to one end of the telescopic rod, and a slider is fixedly connected to the outside of the tension sensor. An adjusting rod is fixedly connected to one end of the operating handle, and an adjusting groove is provided on the outside of the adjusting rod. A sliding sleeve is movably connected to the adjusting rod through the adjusting groove, and a fixing sleeve is fixedly connected to one end of the adjusting rod.

[0008] The expansion unit includes a connecting rod fixedly connected to the outside of the sliding sleeve and the fixed sleeve. The bottom end of the connecting rod has an installation groove, and an adjusting arm is installed inside the installation groove. The bottom end of the adjusting arm is fixedly connected to a screw.

[0009] Preferably, an operation button is installed on the outer side of the operating grip, and a display screen is embedded on the outer side of the operating grip away from the operation button.

[0010] Preferably, the slider is movably connected to the adjusting rod, the slider is fixedly connected to the sliding sleeve, and the slider is located inside the adjusting rod.

[0011] Preferably, the adjusting rod is made of metal material and has a smooth outer surface.

[0012] Preferably, one side of the connecting rod is threaded with an adjusting screw, and the connecting rod is fixedly connected to the adjusting arm through the adjusting screw.

[0013] Preferably, a threaded sleeve is threaded to the outer side of the screw, a fixing block is fixedly connected to the bottom end of the threaded sleeve, and a support plate is fixedly connected to one side of the fixing block.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This utility model, through the design of a telescopic rod, a tension sensor, and a slider, allows the operator to loosen the adjusting screw according to the desired expansion when using the medical animal experimental retractor. The operator can then push or pull the adjusting arm, which moves via the mounting groove on the connecting rod, allowing adjustment of the angle of the retractor plate. After adjustment, the retractor plate is positioned at the soft tissue location requiring expansion. The operator then activates the telescopic rod via an operating button. The telescopic rod, through the tension sensor, moves the slider, which in turn moves the sliding sleeve. The two retractor plates then expand the animal's soft tissue. During the expansion process, the tension sensor monitors the expansion force and displays it on the screen. Once the expansion force is reached, the telescopic rod stops. If the expansion force is insufficient, the telescopic rod automatically activates to increase the expansion force. This avoids over-expansion causing tissue damage and insufficient expansion affecting the surgical field, ensuring adequate exposure of the surgical field. Attached Figure Description

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0023] In the description of this patent, it should be understood that the terms “center,” “upper,” “lower,” “front,” “back,” “left,” “right,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” and “outer,” etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this patent and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this patent.

[0024] As attached Figure 1 To be continued Figure 4 As shown:

[0025] Example 1: A medical animal experimental retractor includes an operating unit 1 for operating the retractor, comprising an operating handle 101 for the operator to grip, a lithium battery 108 for power supply and adjustment, and a telescopic rod 109. One end of the telescopic rod 109 is fixedly connected to a tension sensor 110 for monitoring the retracting force, and a slider 111 for limiting is fixedly connected to the outside of the tension sensor 110. One end of the operating handle 101 is fixedly connected to an adjusting rod 104 for sliding a sliding sleeve 106. An adjusting groove 105 for limiting is provided on the outside of the adjusting rod 104. The adjusting rod 104 is movably connected to the sliding sleeve 106 for moving the retracting component through the adjusting groove 105. One end of the adjusting rod 104 is fixedly connected to a fixing sleeve 107 for fixing.

[0026] Furthermore, an operation button 102 for activating the spreader is installed on the outer side of the operating grip 101, and a display screen 103 for displaying the spreading force is embedded on the outer side of the operating grip 101 away from the operation button 102.

[0027] Furthermore, slider 111 is movably connected to adjusting rod 104, slider 111 is fixedly connected to sliding sleeve 106, and slider 111 is located inside adjusting rod 104.

[0028] Furthermore, the adjusting rod 104 is made of metal and has a smooth outer surface.

[0029] As can be seen from the above, by operating button 102 to start telescopic rod 109, telescopic rod 109 drives slider 111 to move through tension sensor 110. At the same time, slider 111 drives sliding sleeve 106 to move. The two spreading plates 208 will then spread the soft tissue of the animal. During the spreading process, tension sensor 110 will monitor the spreading force and display it on display screen 103. When the spreading force is reached, telescopic rod 109 stops running. If the spreading force is insufficient, telescopic rod 109 will automatically start to increase the spreading force.

[0030] Example 2: This example is basically the same as the previous example, except that the stretching unit 2 for stretching soft tissue includes a connecting rod 201 for installing the stretching component, which is fixedly connected to the outside of the sliding sleeve 106 and the fixed sleeve 107. The bottom end of the connecting rod 201 is provided with a mounting groove 203. An adjusting arm 204 for adjustment is installed on the inner side of the mounting groove 203. The bottom end of the adjusting arm 204 is fixedly connected with a screw 205 for connection and fixation.

[0031] Furthermore, one side of the connecting rod 201 is threaded with an adjusting screw 202 that adjusts the adjusting arm 204, and the connecting rod 201 is fixedly connected to the adjusting arm 204 through the adjusting screw 202.

[0032] Furthermore, the outer thread of the screw 205 is connected to a threaded sleeve 206, which serves as a connection. The bottom end of the threaded sleeve 206 is fixedly connected to a fixing block 207 for installing the expansion plate 208. The side of the fixing block 207 is fixedly connected to the expansion plate 208, which expands the soft tissue.

[0033] As can be seen from the above, when using the medical animal experiment spreader, the operator loosens the adjusting screw 202 according to the spreading requirements, and then the staff can push and pull the adjusting arm 204. The adjusting arm 204 can move through the mounting groove 203 on the connecting rod 201, and at this time the angle of the spreading plate 208 can be adjusted.
