Description

Technical Field

[0001] The utility model belongs to the technical field of animal experimental devices, and in particular relates to a traction device for animal experimental surgery. Background Art

[0002] When performing surgery on experimental animals, one or two assistants are often required to use hemostats to pull the animal's skin, fascia, or muscle tissue from two or more directions to expand the wound or fully expose the surgical field. Assistants must keep their hands suspended in mid-air for extended periods, which can easily lead to numbness and soreness. Even the slightest tremor or deviation can affect the surgical procedure. However, commonly used surgical instruments and traction devices for experimental animals have a relatively fixed range, incomplete traction directions, and limited functionality. They also lack real-time image transmission and sometimes require external components to illuminate, magnify, or image a specific area of ​​the surgical field.

[0003] Patent CN216985273U discloses a retractor for experimental animal surgery. Because the retractor ring has a fixed diameter, the size of the surgical incision it can accommodate is relatively constant. The retractor blades must be inserted into the retractor buckle before they can engage the incision. This results in unstable retraction and non-adjustable angles, limiting its application. Therefore, there is a need for an improved retractor device for experimental animal surgery to address these issues. Utility Model Content

[0004] The utility model aims to provide a traction device for animal experimental surgery, which can adjust the operating range and angle of the hemostatic forceps through a support arm and a mechanical arm, thereby achieving hemostasis or all-round traction of the surgical site.

[0005] To achieve the above-mentioned purpose, the utility model provides a traction device for animal experimental surgery, comprising a fixed base, a support arm, an endoscope, a fixing clamp, two mechanical arms and a clamping assembly;

[0006] One end of the support arm is fixed to the fixed base, and the other end is connected to the endoscope; one end of the fixing clamp is movably connected to the support arm, and the other end is fixedly connected to the robotic arm for adjusting the position of the robotic arm; the clamping assembly is connected to the robotic arm for stopping bleeding or pulling the surgical site.

[0007] Furthermore, the support arm includes a hollow serpentine support tube and a holder; one end of the serpentine support tube is connected to the fixed base, and the other end is connected to the holder; the endoscope is connected to the holder;

[0008] The serpentine support tube can be bent and shaped in any direction to adjust the angle of the endoscope and the fixing clamp.

[0009] Furthermore, the endoscope includes a camera module and a data connector, and the camera module is connected to the fixer; the data connector is arranged at the fixed base and is connected to the camera module through a data cable, and the data cable passes through the interior of the serpentine support tube of the hollow structure and is led out from the fixed base.

[0010] Furthermore, the fixing sleeve is provided on the support arm and is locked by a knob, and is used for being moved and rotated on the support arm to a target position and then locked.

[0011] Furthermore, the robotic arm is fixed to the fixing clamp by screws, and each of the robotic arms includes three sets of universal heads for adjusting the angle of the clamping assembly.

[0012] Furthermore, the clamping assembly includes a fixed joint fixedly connected to each of the robotic arms and a clamper connected to the fixed joint.

[0013] Furthermore, the clamp is a hemostatic forceps.

[0014] Furthermore, the fixed joint is also connected to an optical module, and the optical module is connected to the fixed joint through a universal hose and a rigid straight screw.

[0015] Furthermore, the optical module includes two optical magnifiers movably connected to the ends of the rigid straight screw.

[0016] Furthermore, the fixed base includes an upper splint, a lower splint, a stud and a knob, and a screw hole is provided above the stud for threaded connection with the support arm; the bottom of the stud is fixedly connected to the lower splint, and the upper splint and the knob are sleeved on the stud, and the position of the upper splint is adjusted by rotating the knob, so as to clamp or loosen it with the lower splint.

An endoscope is installed at the end of the support arm, and its orientation can be adjusted to assist in observing the experimental site, facilitating the smooth progress of the experiment.

[0019] 2. By configuring the support arm as a hollow, serpentine support tube structure that can be bent and shaped in any direction, the camera module's position can be adjusted by bending. The hollow structure also facilitates the connection and protection of the endoscope's data cable, saving space. The data connector is located at the fixed base, preventing interference with the camera module due to proximity.

[0020] 3. By connecting the endoscope to external electronic devices, real-time image transmission and broadcasting can be achieved.

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

[0026] See also Figure 1 and 2 The present invention provides a traction device for animal experimental surgery, comprising a fixed base 1, a support arm 2, an endoscope 3, a fixing clamp 4, two robotic arms 5, and a clamping assembly. One end of the support arm 2 is fixed to the fixed base 1, and the other end is connected to the endoscope 3. One end of the fixing clamp 4 is movably connected to the support arm 2, and the other end is fixedly connected to the robotic arm 5 for adjusting the position of the robotic arm 5. The clamping assembly is connected to the robotic arm 5 and is used to stop bleeding or traction the surgical site.

[0027] In this configuration, the fixed base 1 is used to be detachably fixed to an external fixed component, thereby facilitating traction during animal experiments. The external fixed component is a flat tabletop such as a rabbit table, a mouse table, or a laboratory table. The fixing clamp 4 can move along the long axis of the support arm 2 to adjust the position, and can rotate around the support arm 2 to change the orientation. After reaching the target position and angle, it is fixed to the support arm 2, and the position of the robotic arm 5 is also determined accordingly. Then, the clamping assembly connected to the robotic arm 5 is used to stop bleeding or traction the surgical site to achieve the corresponding operation. At the same time, the endoscope 3 can observe real-time images of the specified field of view, and take photos or videos, which helps to smoothly carry out the experiment.

[0028] Specifically, the fixed base 1 includes an upper plate, a lower plate, a stud, and a knob. A threaded opening is provided above the stud for threaded connection with the support arm 2. The bottom of the stud is fixedly connected to the lower plate. The upper plate and knob are movably mounted on the stud. The upper plate is adjusted in position by rotating the knob, thereby tightening or loosening the upper plate. When fixed, the upper and lower plates are respectively located above and below the external fixed component. By rotating the knob downward, the upper plate is pressed downward, thereby being fixed to the fixed component. In particular, each plate is provided with an anti-slip pad on the contact surface with the tabletop to increase friction.

[0029] The support arm 2 includes a hollow serpentine support tube 21 and a fixer 22; one end of the serpentine support tube 21 is connected to the fixed base 1, and the other end is connected to the fixer 22; the endoscope 3 is connected to the fixer 22; the serpentine support tube 21 can be bent and shaped in any direction, for example, a metal hose is selected to adjust the angle of the endoscope 3 and the fixing clamp 4.

[0030] The endoscope 3 includes a camera module 31 and a data connector 32. The camera module 31 is connected to the fixture 22. The end of the fixture 22 has a fixing screw that can adjust the length of the endoscope 3 extending out of the support arm 2. The data connector 32 is arranged at the fixed base 1 and is connected to the camera module 31 through a data cable. The data cable passes through the interior of the hollow structure serpentine support tube 21 and is led out from the fixed base 1. The data cable can be bent and shaped at will to adapt to the bending of the serpentine support tube 21. The tail end of the data connector 32 is equipped with a USB / Type-C connector for connecting to external electronic devices and transmitting images. The camera module can automatically focus and has 8 LED lights with adjustable brightness.

[0031] Such a configuration can save space, prevent the data line from being damaged, and adjust the position of the camera module 31 through the serpentine support tube 21.

[0032] The crab-claw-shaped retaining clip 4 is mounted on the support arm 2 and locked with a knob. It is used to move and rotate on the support arm 2 to the target position and then lock it. The retaining clip has two screw holes that can be connected to the robotic arm 5 via screws. The position of the robotic arm 5 can be adjusted by moving and rotating the retaining clip 4.

[0033] Two robotic arms 5 are fixed to the fixing clamp 4 by screws. Each robotic arm 5 includes three sets of universal heads, such as Figure 1 The first, second, and third universal heads 51, 52, 53 are connected by a connecting rod to adjust the angle of the clamping assembly. The two sets of robotic arms 5 and clamping assemblies increase the pulling range and flexibility. Multiple clamping assemblies can also be combined by installing multiple sets of fixing clamps 4 on the support arm 2.

[0034] The clamping assembly includes a fixed joint 6 fixedly connected to each of the robotic arms 5 and a clamp 7 connected to the fixed joint 6. The fixed joint 6 is connected to the end of the third universal head 53. The clamp 7 is a hemostat or similar device that can be engaged and has functions such as pulling and stopping bleeding.

[0035] The fixed joint 6 uses a knob to secure one arm of the gripper 7 between the two baffles, allowing the gripper to operate in either a perpendicular or parallel direction to the baffle plane without affecting the opening and closing of the gripper 7. There are two additional screw holes, one for connecting to the robotic arm 5 and the other for connecting to the optical module 8 or other modules to expand functionality.

[0036] The fixed joint 6 is further connected to an optical module 8 , which is connected to the fixed joint 6 via a universal hose 9 and a rigid straight screw.

[0037] The optical module 8 includes two optical magnifying glasses movably connected to the ends of the rigid straight screw, both of which can rotate perpendicular to the long axis of the rigid straight screw. Each lens can magnify 5 times, and the two lenses combined can magnify 10 times.

[0038] The specific working process of the present utility model is as follows: first place the upper and lower clamps of the fixed base 1 on the upper and lower surfaces of the experimental table respectively, and fix the device on the experimental table by the knob. Rotate the support arm 2 so that it covers the experimental operation area, and adjust it to a suitable operating height by bending the support arm 2. Adjust the position of the fixing clamp 4 on the support arm 2 along the long axis direction of the support arm 2 so that the clamp reaches the required pulling range, and then rotate it around the peripheral wall of the support arm 2, and adjust the fixing clamp 4 so that the screw hole at its lower end is exposed in a suitable position for easy connection of the robotic arm 5. Fix it to the fixing clamp 4 with the screws on the robotic arm 5, and then adjust the angle of the robotic arm 5 so that it reaches above the desired pulling part. Select a hemostatic forceps of appropriate size, and fix one arm of the hemostatic forceps to the fixed joint 6 with the screws on the fixed joint 6. Pull the operating part by operating the hemostatic forceps, or clamp to stop bleeding.

[0039] Adjust the universal tube of optical module 8 and position the optical element on top of it at the desired observation area. Observation with one lens provides 5x magnification, and observation with two lenses stacked together provides 10x magnification, making observation and operation easier. Adjust the position and angle of endoscope 3 and connect it to an external electronic device via the USB / Type-C connector at the rear. Observe the real-time image of the specified field of view on a mobile phone, tablet, or computer, and take photos or videos. Digital image magnification can make the field of view clearer, and the brightness of the endoscope's LED light can make the field of view brighter. Connect other components through the screw holes on the fixed connector 6 to expand the other functions of this device.

[0040] In summary, this animal experimental surgical traction device can be used alone or in combination. It has a large traction range and the angle can be adjusted at will. It can perform local hemostasis, lighting, and optical magnification. It can also be connected to external equipment to perform real-time digital image magnification, broadcasting, recording and other functions. The fixed joint 6 also has a screw hole to connect other instruments or components to expand its functions.

[0041] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
