Description

Organ puncture fixing needle for laparoscope

Technical Field

The utility model relates to a medical equipment technique, in particular to a technique of an organ puncture fixing needle for laparoscope.

Background

When performing laparoscopic surgery, it is often necessary to suture and fix an organ or tissue adjacent to the surgical site in advance so as not to affect the appearance and operation of the surgical site. For example, in laparoscopic surgery for female patients with rectal cancer, the uterus is often lifted toward the abdominal wall or fixed to the anterior abdominal wall by suturing, so that the rectum is exposed and the operation is not affected.

The method adopted in the laparoscopic surgery at present is to penetrate a straight needle with a suture at the tail part and about 8 cm in length from the abdominal wall, after the straight needle enters the abdominal cavity, puncture the organ (or tissue) to be suspended, then penetrate the straight needle from the inner side of the abdominal wall to the outer side of the abdominal wall, tighten the suture outside the abdominal wall and tie a knot, thus fixing the organ (or tissue) to be suspended on the anterior abdominal wall. However, the method needs a straight needle about 8 cm long to repeatedly puncture the abdominal cavity, so the operation is complicated, the operation time is long, and the tissue damage is also large.

SUMMERY OF THE UTILITY MODEL

To the defect that exists among the above-mentioned prior art, the utility model aims to solve the technical problem that a organ puncture fixing needle for peritoneoscope is provided, which is easy and simple to handle, can shorten the operation time, and reduces the tissue damage.

In order to solve the technical problem, the utility model provides a fixed needle of organ puncture for peritoneoscope which characterized in that: comprises a straight needle body; the lower end of the needle body is provided with a sharp needle tip part, the needle tip part is provided with a line inserting groove which is opened towards the upper left direction, and the upper end of the needle body is radially expanded to form a columnar needle handle;

the needle body is provided with a lock rod capable of sliding up and down and a guide groove for guiding the lock rod to slide up and down, a vertical rod hole is formed in the needle handle, and the upper part of the lock rod is inserted into the rod hole in the needle handle in a sliding fit manner;

the outer wall of the needle handle is provided with a driving sliding block capable of sliding up and down, the needle handle is provided with a vertical strip-shaped through hole, and the inner end of the driving sliding block extends into a rod hole in the needle handle through the through hole on the needle handle and is fixedly connected with the upper part of the lock rod;

when the locking rod slides upwards to an upper dead point, the lower end of the locking rod is flush with the upper side groove edge of the wire embedding groove, and when the locking rod slides downwards to a lower dead point, the lower end of the locking rod props against the lower side groove edge of the wire embedding groove;

the lower part of the needle handle is sleeved with an elastic protection pad which is annular, the needle handle penetrates through the inner ring of the protection pad, and the needle handle is tightly matched with the protection pad.

The utility model provides a fixed needle of organ puncture for peritoneoscope, can go into the rule slot of needle point portion with medical suture card, implement to draw needle point portion in the abdominal cavity, the operation of outside needle handle is deuterogamied, usable needle body is direct to fix target organ or tissue in required position, the elasticity protection pad of needle handle lower part can support abdominal cavity outer wall skin, play the fulcrum effect, do benefit to the operation, have characteristics easy and simple to handle, can shorten the operation time, and also need not the puncture of making a round trip, can reduce the tissue damage.

Drawings

FIG. 1 is a schematic structural view showing an open state of a wire insertion groove in an organ puncture fixing needle for laparoscope according to an embodiment of the present invention;

fig. 2 is a schematic structural view illustrating a closed state of a thread insertion groove in an organ puncture fixing needle for laparoscope according to an embodiment of the present invention.

Detailed Description

The following description will be made in detail with reference to the accompanying drawings, but the present embodiment is not intended to limit the present invention, and all similar structures and similar variations thereof adopted by the present invention should be included in the protection scope of the present invention, and the relations between the numbers of the components in the present invention are shown.

As shown in fig. 1-2, an organ puncture fixing needle for laparoscope provided by the embodiment of the present invention is characterized in that: comprises a straight needle body 1; a sharp needle tip part 3 is formed at the lower end of the needle body 1, a line inserting groove 8 which is open towards the upper left direction is formed at the needle tip part, and the upper end of the needle body is radially expanded to form a columnar needle handle 2;

the needle body 1 is provided with a lock rod 4 capable of sliding up and down and a guide groove for guiding the lock rod 4 to slide up and down, a vertical rod hole is formed in the needle handle 2, and the upper part of the lock rod 4 is inserted into the rod hole in the needle handle in a sliding fit manner;

the outer wall of the needle handle 2 is provided with a driving slide block 6 capable of sliding up and down, the needle handle is provided with a vertical strip-shaped through hole 7, and the inner end of the driving slide block 6 extends into a rod hole in the needle handle through the through hole 7 on the needle handle and is fixedly connected with the upper part of the lock rod 4;
