Medical retractor

Abstract

A medical retractor avoids medical staff continuously operating the medical retractor with hands, greatly liberates the hands of medical staff, reduces labor cost, and can expand a surgical space, more clearly expose a surgical visual field, and be beneficial to a doctor to perform more accurate surgical operation and shorten a surgical time. The medical retractor comprises a clip fixed end (1), a linking sheath (2), a nut position fixed lock (3), a movable rod (4), and a first clip movable end (5). The first clip movable end is connected with an anterior sheath of a rectus abdominis muscle. One end of the movable rod is connected with the clip fixed end. The body of the linking sheath is a hollow rod. The movable rod is inserted into the body of the linking sheath. The movable rod is fixed in the linking sheath by screwing the nut position fixed lock. One side of the clip fixed end is fixed at the top end of the linking sheath, and the other side clamps a fixed object.

Description

Technical Field

[0001] This utility model relates to the technical field of medical devices, and in particular to a medical retractor. Background Technology

[0002] In open abdominal surgery, when patients have a thick layer of fat, a surgeon often needs to manually retract the anterior rectus abdominis sheath to better expose the surgical field. This prevents the surgeon from participating in other surgical tasks, resulting in excessively high labor costs. Therefore, there is an urgent need for a medical retractor that can expose the surgical field, facilitate surgical operations, and eliminate the need for prolonged manipulation by the surgeon. Utility Model Content

[0003] To overcome the shortcomings of the existing technology, the technical problem to be solved by this utility model is to provide a medical retractor that avoids medical staff from continuously operating the medical retractor by hand, greatly freeing up the hands of medical staff, reducing labor costs, expanding the surgical space, exposing the surgical field more clearly, which is conducive to doctors to perform more precise surgical operations and shortening the operation time.

[0004] The technical solution of this utility model is: this medical retractor includes a clamp fixing end, a connecting sheath, a position fixing lock, a movable rod, and a first clamp moving end;

[0005] The first clamp's movable end is connected to the anterior rectus abdominis sheath, and one end of the movable rod is connected to the clamp's fixed end. The body of the connecting sheath is a hollow rod-shaped structure. The movable rod is inserted into the body of the connecting sheath, and the movable rod is fixed inside the connecting sheath by tightening the nut position lock. One side of the clamp's fixed end is fixed to the top of the connecting sheath, and the other side clamps the fixing object.

[0006] The movable end of the clamp in this invention connects to the anterior sheath of the rectus abdominis muscle. Based on the distance between the wound and the fixed object of the clamp in the operating room, and the desired exposure of the surgical field, the movable rod is pulled out of the connecting sheath, and then the movable rod is fixed with the position locking lock, clamping the fixed object with the clamp. This avoids medical staff from continuously operating the medical retractor by hand, greatly freeing up their hands, reducing labor costs, expanding the surgical space, and exposing the surgical field more clearly, which is conducive to doctors to perform more precise surgical operations and shorten the operation time. Attached Figure Description

[0007] Figure 1 This is a schematic diagram of the structure of the medical retractor of this utility model. Detailed Implementation

[0008] like Figure 1 As shown, this medical retractor includes a clamp fixing end 1, a connecting sheath 2, a position fixing lock 3, a movable rod 4, and a first clamp moving end 5;

[0009] The first clamp's movable end is connected to the anterior rectus abdominis sheath, and one end of the movable rod is connected to the clamp's fixed end. The body of the connecting sheath is a hollow rod-shaped structure. The movable rod is inserted into the body of the connecting sheath, and the movable rod is fixed inside the connecting sheath by tightening the nut position lock. One side of the clamp's fixed end is fixed to the top of the connecting sheath, and the other side clamps the fixing object (not shown in the figure).

[0010] The movable end of the clamp in this invention connects to the anterior sheath of the rectus abdominis muscle. Based on the distance between the wound and the fixed object of the clamp in the operating room, and the desired exposure of the surgical field, the movable rod is pulled out of the connecting sheath, and then the movable rod is fixed with the position locking lock, clamping the fixed object with the clamp. This avoids medical staff from continuously operating the medical retractor by hand, greatly freeing up their hands, reducing labor costs, expanding the surgical space, and exposing the surgical field more clearly, which is conducive to doctors to perform more precise surgical operations and shorten the operation time.

[0011] Preferably, the nut position fixing lock is a connecting nut, and after the movable rod is of a certain length, the connecting nut and the movable rod are connected by friction. This structure makes the connection between the movable rod and the connecting sheath more secure.

[0012] Preferably, the end of the movable rod protruding from the connecting sheath has a large ring, and the moving end of the first clamp includes a force-applying part and a clamping part. The force-applying part has a small ring with a notch, through which the large ring passes and the moving end of the first clamp connects to the movable rod. This structure makes it easier to replace the moving end of the first clamp.

[0013] Preferably, the medical retractor further includes a second clamping movable end 6, which includes a force-applying part and a clamping part. The force-applying part has a small ring with a notch, through which a large ring passes. The second clamping movable end is connected to a movable rod. Using two clamping movable ends, forming a triangle with the fixed object, results in a more stable connection. The specific working process of this medical retractor is as follows:

[0014] 1. Adjust the moving ends of the two clamps to a suitable angle, clamp the patient's anterior sheath, and pull up the connecting sheath.

[0015] 2. Adjust the connecting sheath and movable rod to the appropriate length using the connecting nut, and tighten the nut to fix the length.

[0016] 3. Secure the distal surgical drape with the clamping end. If you wish to further adjust and expand the surgical field, you can also clamp the clamping end to the anesthesia stent.

[0017] This medical retractor is suitable not only for cesarean sections but also for other open abdominal surgeries.

[0018] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the protection scope of the present utility model.
