Description

Suture puncture needle

Technical Field

The utility model relates to the field of medical appliances, in particular to a suture puncture needle.

Background

Laparoscopic surgery is a minimally invasive surgical method newly developed in recent years and is widely applied to surgical operations. Laparoscopic surgery is a procedure that utilizes a laparoscope and its associated instruments. The cold light source is used for providing illumination, the laparoscope lens is inserted into the abdominal cavity, and the digital camera technology is used for leading the image shot by the laparoscope lens to be transmitted to a post-stage signal processing system through an optical fiber and displaying the image on a special monitor in real time. Then, the doctor analyzes and judges the state of the patient through images of different angles of the patient organ displayed on the monitor screen, and performs the operation by using a special laparoscope instrument.

The fascia closer is usually adopted for suturing after laparoscopic surgery, but the fascia closer has a complex structure and a thick shell, and an incision needs to be correspondingly enlarged, so that a large wound is caused after the surgery.

The utility model provides a suture pjncture needle, includes suture pjncture needle main part, suture pjncture needle main part is equipped with wire feeding groove and lead wire groove, wire feeding groove notch orientation suture pjncture needle main part head, the lead wire groove notch is sewed up pjncture needle main part head dorsad, the head of suturing pjncture needle main part is equipped with the recess, the recess bottom is fixed with the spring, spring one end is connected with the protective sheath.

Preferably, the thread feeding groove and the thread guiding groove are respectively arranged at two sides of the suture puncture needle main body.

Preferably, the metal shaft sleeve is arranged in the protective sleeve, and a silica gel layer is coated outside the metal shaft sleeve.

Preferably, the spring is a variable pitch spring.

The suture puncture needle has the following effects:

1. the structure is simple, the fascia closer with a complex structure can be replaced, and the postoperative wound is small;

2. the protective sleeve arranged at the head of the suture puncture needle main body can pop out after entering the abdominal cavity, thereby protecting the viscera from being punctured by the needle point.

Detailed Description

In order to facilitate understanding of the present invention, the present invention will be described more fully hereinafter with reference to the accompanying drawings. The preferred embodiments of the present invention are shown in the drawings. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

The same or similar reference numerals in the drawings of the embodiments of the present invention correspond to the same or similar parts; in the description of the present invention, it should be understood that if the terms "upper", "lower", "left", "right", "inner", "outer", etc. are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, it is only for convenience of description and simplification of description, but it is not indicated or implied that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and therefore, the terms describing the positional relationship in the drawings are used only for illustrative purposes and are not to be construed as limiting the present patent, and the specific meaning of the terms will be understood by those skilled in the art according to the specific circumstances.

In the description of the present invention, unless otherwise explicitly specified or limited, the term "connected" or the like, if appearing to indicate a connection relationship between the components, is to be understood broadly, for example, as being either a fixed connection, a detachable connection, or an integral part; can be mechanically or electrically connected; they may be directly connected or indirectly connected through intervening media, or may be connected through one or more other components or may be in an interactive relationship with one another. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

The suture puncture needle shown in fig. 1 and 3 comprises a suture puncture needle body 1, wherein the suture puncture needle body 1 is provided with a wire feeding groove 11 and a wire leading groove 12, the notch of the wire feeding groove 11 faces to the head 14 of the suture puncture needle body 1, the notch of the wire leading groove 12 faces away from the head 14 of the suture puncture needle body 1, the head 14 of the suture puncture needle body 1 is provided with a groove 13, a spring 3 is fixed at the bottom of the groove 13, and one end of the spring 3 is connected with a protective sleeve 2.

Preferably, the thread feeding groove 11 and the thread guiding groove 12 are respectively disposed at both sides of the suture puncture needle body 1, the grooves formed at both sides reduce the bending-resistant cross-sectional area, and in order to improve the overall rigidity, the thread feeding groove 11 and the thread guiding groove 12 are respectively disposed at both sides of the suture puncture needle body 1 and spaced apart by a certain axial distance.

Preferably, a metal shaft sleeve 21 is arranged in the protective sleeve 2, a silica gel layer 22 is coated outside the metal shaft sleeve 21, and the silica gel layer 22 plays a sealing role and prevents liquid from entering the groove 13 to cause the spring 3 to rust.

Preferably, the spring 3 is a variable-pitch spring, the spring 3 is used for freely extending after the pressure of the suture puncture needle is lost after the suture puncture needle enters the abdominal cavity, the protective sleeve is pushed out to the position covering the head 14 of the suture puncture needle main body 1, in order to reduce the resistance of the suture puncture needle, the spring 3 is the variable-pitch spring, the pitch of the middle part of the variable-pitch spring is larger than the pitches of the two ends of the variable-pitch spring, so that the smaller pressure reaches the same deformation, and the controllability is improved.

The specific working principle of this embodiment is as follows:

the suture is clamped into the suture sending groove 11, the needle inserting angle is 65-70 degrees under the assistance of a laparoscope, and the force is acted on the needle point to send the suture into the abdominal cavity. The protective sleeve 2 of the suture puncture needle main body is contracted into the groove 13 under the resistance of abdominal wall muscles, the suture needle penetrates through the abdominal wall tissue on one side and is sent into the abdominal cavity, then the suture thread is clamped by the operation forceps, the suture needle is drawn out and then penetrates through the abdominal wall tissue on the other side at the same needle inserting angle, the suture thread is clamped into the lead slot 12 by the operation forceps, then the suture needle is drawn out, and finally the suture thread is knotted after the suture is finished.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
