Problems solved by technology

While this single-device approach is generally desirable, it makes the cost of the instrument considerably high, does not allow for modification of the individual steps in the surgical treatment of hemorrhoids, and does not allow the use of surgical techniques deemed most appropriate for the patient (e.g., suturing by suture). instead of staples for tissue fixation, or for tissue resection with radiofrequency or ultrasonic energy instead of circular cutting)

Embodiment Construction

[0039] With reference to the accompanying drawings, figure 1 is a general isometric view of the surgical tissue clamp 1 according to the first embodiment. The tissue clamp 1 comprises a collet 2 in its distal region and a handle 3 in its proximal region. The handle 3 and collet 2 are connected by a straight rigid insertion shaft 4 suitable for transanal insertion and positioning of the collet 2 by manual manipulation of the handle 3 held outside the patient's body.

[0040] The collet 2 comprises a proximal jaw 5 rigidly connected to the distal end of a hollow tubular insertion shaft 4 and a distal jaw 6 connected to the distal end of a pull rod 7 which The proximal end of the cartridge is slidably received within the insertion shaft 4 so that the jaws can move relative to each other and cooperate with each other for gripping prolapsed tissue in a substantially radial orientation with respect to the longitudinal axis X of the chuck 2 . The tissue clamp 1 also includes an act...

Abstract

The present invention discloses a surgical tissue clamp (1) for holding prolapsed tissue (10, 10') during a hemorrhoidopexy or hemorrhoidectomy, comprises an elongate insertion shaft (4), a handle (3) and a clamping head (2) including a proximal jaw (5) and a distal jaw (6) configured to cooperate with the proximal jaw (5) for clamping the prolapsed tissue (10), as well as an actuating device (8)operatively connected with the proximal and distal jaws (5, 6) and adapted to approximate the jaws and to hold the jaws in a tissue clamping configuration. The clamping head (2) defines at least one proximal access aperture (11) configured to expose the clamped tissue proximally.

Description

technical field [0001] The present invention relates generally to surgical instruments for the treatment of hemorrhoids, and more particularly, to a tissue clamp that enables transanal hemorrhoidoplasty or hemorrhoidectomy procedures to reposition internal hemorrhoids to their natural anatomy location and / or partial or total removal of internal hemorrhoids in patients with mucosal prolapse. Background technique [0002] Hemorrhoids (hemorrhoids) are caused by congestion of the internal and / or external venous plexus around the anal canal and are characterized by a more or less pronounced tendency to prolapse temporarily or permanently outside the anal canal. Symptoms associated with hemorrhoids include pain, bleeding, itching, discharge of mucus, and where the prolapsed tissue cannot be manually placed back into the anal canal, the prolapsed tissue is often strangulated or thrombused. [0003] Although hemorrhoids can be treated in many cases with dietary modifications, topi...
