Abstract
The utility model relates to a director is sewed up to deep lacuna, including moulding guide catheter in advance and sewing up the needle, the guide catheter is hollow pipe, moulding guide catheter head end is the circular-arc of erroneous tendency one side in advance, it holds in the palm through the needle and fixes to sew up the needle in the guide catheter, the needle point of sewing up the needle becomes 30 ~ 45 contained angles with guide catheter shaft. The curved guide catheter facilitates penetration of the distal needle through the skin at a distance and prevents the trailing end of the needle from causing unnecessary trauma to the tissue as it is penetrated outwardly. The utility model has simple structure and convenient use, and is favorable for reducing the operation time.
Description
Technical Field
The utility model belongs to the technical field of medical instruments, in particular to a deep lacuna suture guide.
Background
In order to ensure the beauty of a patient and reduce scars in plastic, reconstructive or cosmetic operations, surgical incisions must be reduced and minimized, so that an orthopedic surgeon often needs to put a suture instrument from a small incision in the skin into a long and narrow subcutaneous deep cavity for precise remote operations, such as suturing, suspending, resetting, fixing and the like. This requires the surgeon to precisely guide the needle out of the distal skin through the subcutaneous compartment during the procedure, which is highly demanding on the operator's surgical technique.
In the prior art, a needle holder is required to clamp a straight suture needle with a thread for operation, and the straight suture needle is thin and sharp, so that when the needle holder pushes the clamped straight suture needle to a specified position through a tunnel for subcutaneous underway stripping, the traveling direction and the position of the straight suture needle are difficult to determine in a mode of direct viewing through an incision or body surface touch. Meanwhile, when the straight suture needle needs to penetrate the skin outwards, an angle is formed between the needle holder and the suture needle, and the tail end of the suture needle may cause unnecessary injury to the tissue.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a guider is sewed up to deep lacuna is provided, the guide is sewed up the needle and is got into deep lacuna postflexion, is convenient for pierce through skin in a distance and sews up.
The utility model provides a technical scheme that its technical problem adopted is: the deep lacuna suture guide comprises a pre-shaped guide catheter and a suture needle, wherein the guide catheter is a hollow catheter, the head end of the pre-shaped guide catheter is in a circular arc shape deviated to one side, the suture needle is fixed in the guide catheter through a needle support, and the needle point of the suture needle and the tube body of the guide catheter form an included angle of 30-45 degrees.
Further, the top end of the guiding catheter is hemispherical.
Furthermore, the top end of the guide catheter is provided with an opening for the suture needle to extend out conveniently.
Furthermore, the cross section of the needle holder is in a circular arc shape matched with the head end of the guide tube.
Further, the needle holder is movable.
Advantageous effects
The curved guide catheter facilitates the distal needle to pierce the skin at a distance and prevents the trailing end of the needle from causing unnecessary injury to the tissue when it is pierced outward. The utility model discloses simple structure, convenient to use are favorable to reducing the operation time.
Drawings
FIG. 1 is a deep lacuna suture guide.
Wherein, 1-guiding the catheter; 2-needle holder; 3-suture needle.
Detailed Description
The present invention will be further described with reference to the following specific examples. It should be understood that these examples are only for illustrating the present invention and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes and modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope of the appended claims.
The utility model provides a guide is sewed up to deep lacuna, including moulding guide catheter 1 and sewing needle 3 in advance, guide catheter 1 is hollow pipe, 1 head end of moulding guide catheter is the circular-arc of partial one side in advance, sewing needle 3 holds in the palm 2 through the needle and fixes in the guide catheter 1, the needle point of sewing needle 3 becomes 30 ~ 45 contained angles with 1 shaft of guide catheter. The curved guide catheter 1 makes it easier for the distal needle 3 to pierce the skin at a remote site, and placing the needle 3 completely inside the guide catheter 1 prevents the trailing end of the needle 3 from causing unnecessary damage to the tissue when it is pierced outward.
Further, the top end of the guiding catheter 1 is hemispherical, so that the head end of the guiding catheter 1 is prevented from damaging the tissues when entering the deep cavity.
Further, the top end of the guiding catheter 1 is provided with an opening for allowing the suture needle 3 to extend out, and at the same time, the guiding catheter can provide a guide for the needle point of the suture needle 3.
Further, the cross-sectional shape of the needle holder 2 is a circular arc shape matching with the head end of the guide catheter 1.
In another embodiment, the needle holder 2 is movable and can be connected with a control rod extending from the tail end of the guide catheter 1 as required to control the forward or backward movement of the needle holder 2 and the movement of the suture needle 3 into or out of the guide catheter 1.
