specific Embodiment approach 1

[0007] Specific implementation mode one: combine Figure 1 to Figure 7 Describe this embodiment, the catheter jaw of this embodiment includes an outer torsion ring 9, an inner torsion ring 10, an inner ring end cover 23, two connectors 5, two sleeve-type linear motion bearings 7, and two compression springs 12 , two clamping discs 13, two electromagnets 15, six thrust sensors 14, four torsion sensors 19, two fasteners 1, two sliding sleeves 2, four deep groove ball bearings 3, two One outer end cover 4, two inner sleeves 6, two spring fixing parts 11, four pulleys 16, four pulley shafts 17, two steel wire ropes 18, two circlips 24 and two armatures 25; each The connecting piece 5 is provided with an axial central shoulder through hole, and each connecting piece 5 is made of an integral large flange 5-1, a small flange 5-2, and is arranged on the large flange 5-1 and the small flange. The transition sleeve 5-3 between the disks 5-2 is composed of the large flanges 5-1 of the t...

specific Embodiment approach 2

[0011] Specific implementation mode two: combination figure 1To describe this embodiment, the axial central through hole of the inner torsion ring 10 and the inner ring end cover 23 of this embodiment is arranged coaxially. Such arrangement facilitates the penetration of the catheter 30 . Others are the same as in the first embodiment.

specific Embodiment approach 3

[0012] Specific implementation mode three: combination figure 1 and Figure 4 Describe this embodiment, the difference between this embodiment and specific embodiment 1 is: the conduit jaw of this embodiment also includes four fixed shafts 20; -1 is affixed to the inner ring cover 23-1. Such setting has the advantage of reliable connection.

Abstract

The invention discloses an intervention operation catheter clamping jaw with dual force feedback function, which relates to an intervention operation catheter clamping jaw and solves the problem that a minimally-invasive intervention operation catheter conveying device cannot feed back a push-pull force and a torsional force at the same time. Compression springs are fixedly connected in symmetrically placed spring fixing pieces, clamping disks are connected on the compression springs, a catheter is clamped through the two clamping disks, the clamping disks are connected with armatures through steel wire ropes, the armatures are arranged opposite to electromagnets, the spring fixing pieces and the electromagnets are fixed on an inner torsional ring and an inner ring end cover, an inner torsional rotating shaft and an inner ring shaft are matched with an inner ring of a deep groove ball bearing, a sliding sleeve is sleeved on an outer ring of the deep groove ball bearing, the sliding sleeve is matched with an inner ring of a sleeve type linear motion bearing, the linear motion bearing is fixed on a connector, a push sensor is arranged on the connector, and a torsional force sensor is arranged on the inner torsional ring. The intervention operation catheter clamping jaw realizes clamping, push-pull and torsional dual force feedback function of the intervention operation catheter.

Description

technical field [0001] The invention relates to a clamping jaw for an interventional operation catheter, in particular to a clamping jaw which is used for conveying catheters in minimally invasive interventional operations and has dual force feedback functions. Background technique [0002] Minimally invasive interventional surgery is one of the main means of clinical treatment in hospitals at present. It has the characteristics of no surgery, small trauma, quick recovery and good effect. It will become one of the most promising clinical medical specialties in the 21st century. Catheters are the most important tool in interventional procedures, and traditionally, catheters are manually delivered into the patient's body. This requires doctors to have rich clinical experience, and must perform the operation on the spot, so they will inevitably be injured by radiation. Therefore, interventional surgery has gradually realized remote operation, that is, doctors are far away from...
