Description

Sterile retractor

Technical Field

The utility model relates to the field of medical equipment, concretely relates to aseptic retractor.

Background

A retractor is a surgical medical instrument. When an operation is performed on an affected part in the body of a patient, sometimes an incision needs to be made on the skin, and the incision is retracted by using a retractor so as to expose the affected part, so that the operation is convenient.

CN203647397U discloses an elastic skin retractor, which comprises an elliptical bracket and a retractor, wherein the retractor comprises a retractor head and an elastic retractor handle connected to the retractor head. Symmetrical clamping grooves are formed in the oval support and used for clamping the draw hook; the draw hook handle can be extended and retracted without manual adjustment. However, such retractors have a fixed shape and cannot be adjusted to different patient conditions. The draw hook handle needs to adopt an elastic draw hook, and the universality is poor.

Currently, there is still a need for improved retractor structures.

SUMMERY OF THE UTILITY MODEL

Aiming at the problems in the prior art, the utility model aims to provide a retractor with high universality and convenient use.

In order to achieve the above object, the present invention provides a sterile retractor, comprising: a fixer and a draw hook; the fixer comprises a plurality of supporting plates; the drag hook comprises: a head, and a brace connected to the head; a bayonet used for clamping the brace is arranged on the supporting plate; the brace is provided with a plurality of anti-skid bulges.

Preferably, the fixer further comprises: a stud; the support plates are connected end to end through the studs, and the angle between adjacent support plates is adjusted through the studs.

Preferably, the supporting plate is further provided with: a plurality of buckles.

Preferably, the brace has two anti-slip protrusions, and the two anti-slip protrusions are respectively arranged at one third and two thirds of the position of the brace in the long axis direction.

Preferably, the anti-slip protrusions are annular protrusions surrounding the periphery of the brace.

Preferably, the pull strip is a silica gel pull strip.

Preferably, the length of the brace is 154 mm-164 mm; the outer diameter of the brace is 2.1 mm-3.1 mm.

Compared with the prior art, the beneficial effects of the utility model are that:

(1) the anti-skid protrusions on the pull strip of the retractor can play a role in skid resistance, and the use of medical staff is facilitated. When the draw hook is used for drawing skin, the anti-skid protrusions can also form a blocking effect, so that the brace is clamped in the clamping opening more stably.

(2) The support plate of the retractor is provided with a buckle for clamping a drainage tube or a catheter and the like in some operations.

(3) The support plates of the retractor are provided with the studs, so that the angles between the support plates can be adjusted, and the retractor meets the requirements of operations on different human body parts.

Detailed Description

The technical solution of the present invention will be further explained with reference to the accompanying drawings and examples.

Fig. 1 is a schematic view of a fastener employed in some embodiments. Fig. 2 is a schematic view of the retractor used in some embodiments. Referring to fig. 1 and 2, the sterile retractor is composed of a holder and a retractor 3. The holder comprises a support plate 1. The retractor 3 comprises: a head 31, and a brace 32 connected to the head 31. The support plate 1 is provided with a bayonet 11 for clamping the brace 32; the pull-string 32 has a plurality of anti-slip protrusions 33.

In the retractor 3 shown in fig. 2, the pulling strip 32 has two anti-slip protrusions 33, and the two anti-slip protrusions 33 are respectively arranged at one third and two thirds of the long axis direction of the pulling strip 32. The anti-slip protrusions 33 are annular protrusions around the outer periphery of the stay 32.

The braces 32 are preferably silicone braces 32.

In some embodiments, the length of the riblets 32 is 159mm with a tolerance of no more than 5 mm; the external diameter of the brace 32 is 2.6mm, and the error is not more than 0.5 mm.

The anti-skid protrusions 33 on the pull strip 32 can play a role of anti-skid, and are convenient for medical staff to use. Since the pull strip 32 is clamped into the bayonet 11 of the support plate 1, the anti-slip protrusions 33 can form a blocking effect when the skin is pulled by the pulling hook 3, so that the pull strip 32 is clamped into the bayonet 11 more firmly.

Referring to the holder of fig. 3, in some embodiments, the holder further comprises: a stud 4; the support plates 1 are connected end to end through studs 4, and the angle between adjacent support plates 1 is adjusted through the studs 4. The stud 4 can be a connecting piece such as a screw and the like, and can adjust the angle between the supporting plates 1 and meet the requirements of operations on different human body parts.

The fixer can adopt a plurality of supporting plates 1 to be connected end to end. The structural shape of the supporting plate 1 is designed according to the actual operation requirement. Fig. 4 and 5 show retainers employed in other embodiments.

Referring to fig. 1, in some embodiments, the supporting plate 1 further includes: a plurality of buckles 2. Under the condition that a drainage tube or a catheter needs to be placed in the operation, the corresponding buckle 2 can be configured. The buckle 2 can be designed as a detachable piece, and when no drainage tube or catheter or the like needs to be placed in the operation, the buckle 2 does not need to be configured.

The usage of the retractor is illustrated as follows:

referring to fig. 6, a retractor of corresponding size is selected for the size of the surgical site. Retractors are placed around the surgical site. The incision tissue is pulled open all around through the draw hook, the range size that can pull open according to the incision needs is fixed a position, and the draw hook is straightened, and is fixed with the bayonet socket of silica gel brace embedding retractor. Referring to fig. 7, as the surgery progresses, it is necessary to access deeper tissues. The silicone pull strips can be added or repositioned as desired to maintain the desired angle.

To sum up, the utility model discloses an aseptic retractor's brace is equipped with the non-slip raised, and is convenient to use, is equipped with buckle and double-screw bolt in the backup pad, and the commonality is high.

While the present invention has been described in detail with reference to the preferred embodiments thereof, it should be understood that the above description should not be taken as limiting the present invention. Numerous modifications and alterations to the present invention will become apparent to those skilled in the art upon reading the foregoing description. Accordingly, the scope of the invention should be limited only by the attached claims.
