Description

Bundling vascular forceps for laparoscope

Technical Field

The utility model relates to an operating forceps combined with a cutting instrument, in particular to kinds of special laparoscopic cluster vascular forceps for radical prostatectomy and cystectomy under a laparoscope.

Background

The prostate cancer and the bladder cancer are the most common malignant tumors of urinary surgery, more and more patients are detected in time with the increase of smoking number in China and the improvement of the life quality of people, however, the traditional open surgery has larger trauma and longer recovery time of the patients compared with the laparoscopic surgery, and the patients tend to select the laparoscopic surgery, but due to the limitation of the operating space of the laparoscopic surgery, the traditional surgical instruments are simple and practical, but can be rarely applied to the laparoscopic surgery.

At present, a conventional laparoscope separating clamp, such as a Kangji kj-fl0205wt laparoscope separating clamp, mainly comprises a fixed handle at the rear part, a movable handle, a rotating mechanism, a loop bar and a clamp bar arranged in the loop bar, wherein the front end part of the clamp bar is connected with an open-close arc-shaped jaw and a second jaw through a hinge shaft.

SUMMERY OF THE UTILITY MODEL

The utility model discloses be exactly in order to solve among the prior art when suturing DVC, it is big to lead to the degree of difficulty of suturing because of the unclear blind forceps holder of field of vision in the art, causes hemorrhage, urethral sphincter damage scheduling problem, and provides kinds of peritoneoscope that are more convenient for suturing DVC and uses vascular forceps tied in a bundle.

The utility model discloses a realize according to following technical scheme.

A bundle vessel forceps for laparoscope comprises a loop bar and a forceps bar inside the loop bar, wherein the rear parts of the loop bar and the forceps bar are sleeved with a rotating mechanism, the fixed handle is connected with a movable handle through a frame shaft structure, the front part of the forceps bar is hinged with an inner hinged shaft frame, a hinged shaft and a pull plate are connected with an arc-shaped jaw and a second jaw which are opened and closed, and the ends of the jaw and the second jaw are protruded to the back side to form a jaw leaf and a second jaw leaf with tile-shaped concave surfaces opposite to each other.

The jaw leaf and the second jaw leaf can well converge cluster DVC at , and meanwhile, the surgical suture needle with fixed curvature is tightly attached to the peripheral tube wall formed by folding the smooth jaw leaves, so that the needle can be more easily inserted and withdrawn, the difficulty of endoscopic suture is reduced, and the bleeding risk of separating the two side leaves of the prostate at the later stage is reduced by more complete suture.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and examples.

A bundle vessel forceps for laparoscope comprises a loop bar 1 and a forceps bar 2 therein, wherein the rear parts of the loop bar 1 and the forceps bar 2 are sleeved with a rotating mechanism 3, a fixed handle 4 is connected with a movable handle 5 through a frame shaft structure (not shown), a hinge shaft 6 and a pull plate 9 in a hinge shaft frame 13 at the front part of the forceps bar 2 are connected with an arc-shaped jaw 7 and a second jaw 8 which are opened and closed, and the ends of the jaw 7 and the second jaw 8 are protruded to the back side to form a jaw leaf 10 and a second jaw leaf 11 which are opposite to each other in a tile shape.

The central axis of the folded th jaw leaf 10 and second jaw leaf 11 of the bundled vessel forceps for laparoscope is perpendicular to the axis of the forceps rod 2.

According to the bundle vessel forceps for the laparoscope, the top end parts of the jaw leaves 10 and the second jaw leaves 11 are turned outwards to form corresponding contact plates 12, in the using process in the operation, the contact plates 12 with the turned outwards top ends of the two jaw leaves are mutually supported, contacted and closed during clamping, the dislocation of a clamping opening or the damage to surrounding tissues are avoided, the height of the contact plates 12 is 1/2-2/3 of the height of the jaw leaves, a sutured curved needle is inserted along the back arc of the forceps in the use, and the contact plates 12 are used as needle insertion supports, so that the needle insertion position is more accurate.

Referring to fig. 2 and 3, the cross section of the bundle vascular forceps for laparoscope after the jaw leaves 10 and the second jaw leaves 11 are closed is fusiform, that is, the transverse diameter is larger than the vertical diameter.

The jaw leaves with opposite concave surfaces are in a fusiform shape after being folded, the vertical diameter is 0.8cm, the transverse diameter is 1.4 cm., and the jaw leaves are 0.8cm high, so that the jaw leaves 10 and the second jaw leaves 11 can smoothly pass through a laparoscopic pore channel after being folded.

The th forceps holder leaf and the second forceps holder leaf can well converge cluster DVC at , meanwhile, surgical suture needles with fixed curvature are used, the peripheral tube wall formed by closing and clinging to the smooth forceps holder leaves is easier to insert and withdraw, the difficulty of endoscopic suture is reduced, the bleeding risk of separating the two side leaves of the prostate at the later stage is reduced by more complete suture, more importantly, when the cluster forceps are placed in the operation, the plane between the dorsal vein cluster and the urethra does not need to be dissociated, the electric knife is not forced to cauterize and stop bleeding, the urethral sphincter injury is avoided, compared with the left curved forceps and the grasping forceps under the traditional endoscope, the bleeding risk caused by blind forceps is reduced, the working efficiency of medical staff is improved, the bleeding risk of the patient in the operation is reduced, and better prognosis is obtained.
