Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, specifically to a four-way adjustable retractor for microsurgery of small animal abdomen. Background Technology
[0002] Currently, microsurgical procedures on the abdomen of experimental small animals place extremely high demands on excellent surgical exposure. Therefore, an excellent abdominal surgical retractor can not only open up the abdominal organs but also fully expose the target area.
[0003] Currently, the abdominal retractors we see and use in small animals are mainly bidirectional adjustment instruments, including sliding bidirectional adjustment (such as the GAR100 abdominal retractor) and clamp-type dilatation instruments (such as the GELPI asymmetric retractor). The main feature of traditional small animal exposing instruments is bidirectional exposure; however, as the abdominal cavity is an ex vivo space, bidirectional exposure makes it difficult to fully expose the surgical field. Tissues and organs on both sides of the surgical exposure, especially those perpendicular to the exposing instrument, can still easily obstruct the surgical field and affect surgical procedures.
[0004] Furthermore, current abdominal surgical retractors primarily function to expand the abdomen and do not take into account the operational details of the actual microsurgical process. Current small animal microsurgery, especially procedures such as vascular suturing, requires a large number of microsutures, which restricts the operation of microsurgery. Utility Model Content
[0005] The purpose of this invention is to provide a four-way adjustable retractor for small animal abdominal microsurgery, so as to overcome the problem of poor surgical field exposure caused by the bidirectional expansion of current abdominal exposure instruments.
[0006] The objective of this utility model is achieved through the following technical solution:
[0007] A four-way adjustable microsurgical retractor for small animal abdomen includes two lateral exposure modules and two longitudinal exposure modules, which work together to form a rectangular frame.
[0008] A sliding track runs through the middle of the transverse exposure module along its length, and a transverse auxiliary exposure hook is located at the bottom center.
[0009] The longitudinal exposure module includes a cylindrical slider, with a longitudinal auxiliary exposure hook at the bottom center of the cylindrical slider and fixing nuts at both ends. There are movable adjusting nuts between the longitudinal auxiliary exposure hook and the fixing nuts at both ends.
[0010] Furthermore, a horizontal comb is provided at the top center of the horizontal exposure module, opposite to the horizontal auxiliary exposure hook.
[0011] Furthermore, a longitudinal comb is provided at the top center of the longitudinal exposure module, opposite to the longitudinal auxiliary exposure hook.
[0012] Furthermore, the sliding track has a structure that is thicker at both ends and thinner in the middle.
[0013] Furthermore, the adjusting nut is made of rubber and has a hollow conical structure, and the adjusting nut is sleeved on the cylindrical slider.
[0014] Furthermore, the apex of the adjusting nut is fitted onto the cylindrical slider opposite to the fixing nut.
[0015] Furthermore, the adjusting nut is also provided with threads on its side, which are used in conjunction with the sliding rail of the lateral exposed module.
[0016] Furthermore, the fixing nut is detachably connected to the cylindrical slider.
[0017] In summary, this technical solution has the following advantages:
[0018] This invention provides a four-way adjustable retractor for small animal abdominal microsurgery, comprising a rectangular frame consisting of two lateral exposure modules and two longitudinal exposure modules used in conjunction with each other. A sliding track runs through the middle of the lateral exposure module along its length, and a lateral auxiliary exposure hook is located at the bottom center. The longitudinal exposure module includes a cylindrical slider with a longitudinal auxiliary exposure hook at the bottom center and fixing nuts at both ends. Movable adjusting nuts are provided between the longitudinal auxiliary exposure hook and the fixing nuts at both ends, allowing the retractor to be adjusted in four directions, better overcoming the problem of poor surgical field exposure caused by the bidirectional expansion of current abdominal exposure instruments.
[0019] A transverse comb is located at the top center of the transverse exposure module, opposite to the transverse auxiliary exposure hook. A longitudinal comb is located at the top center of the longitudinal exposure module, opposite to the longitudinal auxiliary exposure hook. By adding microsurgical sutures to the retractor to place the combs, it is easier to manage the sutures during microsurgical suturing and shorten the operation time. Attached Figure Description

[0024] The technical solutions for achieving the purpose of this utility model will be further illustrated below through specific embodiments. It should be noted that the technical solutions claimed by this utility model include, but are not limited to, the following embodiments.
[0025] A four-way adjustable microsurgical retractor for small animal abdomens, such as Figure 1-3 As shown, it includes two horizontal exposure modules and two vertical exposure modules, which work together to form a rectangular frame. It should be noted that... Figure 2 yes Figure 1 A front view with the horizontally exposed module facing the positive direction.
[0026] A sliding track 1 runs through the transverse exposure module along its length in the middle, and a transverse auxiliary exposure hook 3 is located at the bottom center.
[0027] The longitudinal exposure module includes a cylindrical slider 5. The bottom center of the cylindrical slider 5 is provided with a longitudinal auxiliary exposure hook 6 and the two ends are provided with fixing nuts 4, which serve to fix and restrict each module. There are movable adjusting nuts 8 between the longitudinal auxiliary exposure hook 6 and the fixing nuts 4 at both ends, which can make the surgical retractor adjustable in four directions, and better overcome the problem of poor surgical field exposure caused by the bidirectional expansion of current abdominal exposure instruments.
[0028] A transverse comb 2 is located at the top center of the transverse exposure module, opposite to the transverse auxiliary exposure hook 3. A longitudinal comb 7 is located at the top center of the longitudinal exposure module, opposite to the longitudinal auxiliary exposure hook 6. By adding microsurgical sutures to the retractor to place the combs, it is easier to manage the sutures during microsurgical suturing and shorten the operation time.
[0029] The sliding track 1 has a structure that is thicker at both ends and thinner in the middle, and the thickness of the sliding track 1 matches the diameter of the cylindrical slider 5.
[0030] The adjusting nut 8 is made of rubber and has a hollow, conical structure. It is fitted onto the cylindrical slider 5. The adjusting nut 8 is in contact with the sliding rail 1. When the adjusting nut 8 is subjected to a large external force, it deforms, increasing contact with the sliding rail and generating friction to achieve a fixing effect.
[0031] The apex of the adjusting nut 8 is fitted onto the cylindrical slider 5 opposite to the fixing nut 4.
[0032] The adjusting nut 8 is also provided with threads on its side, which are used in conjunction with the sliding rail 1 of the transverse exposed module.
[0033] The fixing nut 4 is detachably connected to the cylindrical slider 5, which facilitates the installation of the surgical retractor and the replacement of the adjusting nut 8.
[0034] In use, two horizontal exposure modules and two vertical exposure modules are interlocked to form a rectangular frame. The horizontal and vertical exposure modules are slid to reach the appropriate size, and the depth of the adjusting nut 8 is rotated to fix the vertical exposure module on the track of the horizontal exposure module.
