Description

Surgical forceps

Technical Field

The utility model relates to the technical field of medical equipment, in particular to an operating forceps for a movable support.

Background

The operation of placing the stent in the lumen of the body of a patient is more and more widely applied, the stent can expand and lead the narrow and blocked blood vessel or lumen to be communicated, solves the traditional operation blind area, has small wound, high curative effect and low risk, and conforms to the direction of medical development. However, since the blood vessel or the lumen is very narrow, the operation difficulty of placing the stent is high, and the situation that the stent placement position is not accurate is often generated. The existing treatment method is to use a small-sized pliers to clamp one end of the stent and move the stent, but the operation difficulty of the pliers is still very high, and because the structure of the stent is usually a cylindrical net or spiral structure, pulling one end of the stent easily causes the deformation and even damage of the stent, which causes waste of materials.

Therefore, the utility model provides a pair of surgical forceps, which comprises an inner tube, an outer sleeve and a forceps body, wherein the inner tube is hollow to form a first cavity through which a guide wire can pass, the outer sleeve is sleeved outside the first part of the inner tube, and a space is arranged between the inner wall of the outer sleeve and the outer wall of the inner tube to form a second cavity through which gas or liquid can pass; the clamp body can be expanded to be in a spherical-bag shape and is positioned outside the second part of the inner tube, one end of the clamp body is connected with the outer wall of the inner tube, and the other end of the clamp body is connected with one end of the outer sleeve to form a spherical or ellipsoidal cavity communicated with the second cavity; the other end of the outer sleeve forms an opening to inject gas or liquid into the cavity of the pincer body through the opening and the second cavity.

Further, the outer surface of the pliers body is covered with a plurality of longitudinally radial rubber strips.

Further, the pliers also comprise a handle on the outer portion of the outer sleeve, and the handle is located on the portion, far away from the pliers body, of the outer sleeve.

Further, the handle is made of rigid materials.

Further, the water bag with the pressure display is further included, and an opening of the water bag is detachably connected to an opening of the outer sleeve.

The utility model provides an operation pincers are through inserting the inside support that removes of support, and the operation degree of difficulty is less, and the adjustment precision is higher, and the whole atress of support is removing in-process non-deformable moreover, has effectively improved the operation effect and has saved the operation material.

Additional aspects and advantages of the invention will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the invention.

Drawings

The above and/or additional aspects and advantages of the present invention will become apparent and readily appreciated from the following description of the embodiments, taken in conjunction with the accompanying drawings of which:

FIG. 1 is a side view of a pair of surgical forceps according to the present invention;

Fig. 2 is a schematic view of the forceps body of the surgical forceps according to the present invention.

Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention more clearly understood, the present invention will be described in further detail with reference to the accompanying drawings and detailed description. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the scope of the present invention is not limited by the specific embodiments disclosed below.

Figure 1 shows a side view of the structure of a forceps according to the invention. The forceps comprise an inner tube 10, an outer sleeve 11 and a forceps body 12, wherein the inner tube 10 is hollow to form a first cavity 101 through which a guide wire can pass, the outer sleeve 11 is sleeved outside a first part of the inner tube 10, and a space is arranged between the inner wall of the outer sleeve 11 and the outer wall of the inner tube 10 to form a second cavity 111 through which gas or liquid can pass. The pincer body 12 is in the shape of a collapsible and inflatable balloon, which is located outside the second portion of the inner tube 10, and one end of which is sealingly connected to the outer wall of the inner tube 10 and the other end of which is connected to the upper end of the outer sleeve 11, so as to form a spherical or ellipsoidal cavity 121 communicating with the second cavity; the lower end of the outer sleeve 11 is formed with an opening to inject gas or liquid into the cavity 121 of the caliper body through the opening and the second cavity 111, thereby inflating the caliper body. The forceps body is made of soft materials such as latex, so that when the surgical forceps are inserted into a urinary catheter, the forceps body is small in size, gas or liquid is filled into the cavity 121 of the forceps body after the surgical forceps are inserted to a preset position, the forceps body can expand, the forceps body abuts against the inner wall of the support from the inside, and the support can be moved through friction force.

Further, in order to increase the friction between the forceps body and the inner wall of the stent, as shown in fig. 2, the outer surface of the forceps body is covered with a plurality of longitudinally radial rubber strips 122, so that when the stent is moved after the forceps body is expanded, the longitudinal friction can be exerted. Optionally, the rubber strip has a rough surface, for example, frosted or provided with a plurality of granular protrusions.

Further, the forceps also include a handle 13 on the exterior of the outer sleeve, the handle being located on a portion of the outer sleeve remote from the forceps body. Optionally, the handle is made of a rigid material, such as a hard plastic, for the operator to hold.

Further, the forceps may also include a balloon or water bladder (not shown) with a pressure display, the opening of the balloon or water bladder being detachably connected to the opening of the outer cannula. The balloon or water bag is connected to the opening of the outer sleeve, and gas or liquid can be injected into the cavity 121 of the forceps body through the second cavity 111, and the inflated state of the forceps body can be maintained.

When the surgical forceps with the practical information is in an initial state, the forceps body is contracted, an operator holds the handle to stretch the surgical forceps into a pipeline for placing the support along the guide wire cavity until the forceps body part enters a cavity in the middle of the support, and then gas or liquid is injected into the cavity of the forceps body through the opening at the other end of the guide pipe, so that the forceps body is expanded into an ellipsoidal shape, the rubber strip on the outer side of the forceps body is attached to the support, and the support can move along with the movement of the surgical forceps due to the fact that the rubber strip has large friction force; when the clamp body is moved to the accurate position, the gas or the liquid in the cavity is exhausted, the clamp body is shrunk, and the clamp body can be drawn out from the support.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit the same; although the present application has been described in detail with reference to the foregoing embodiments, it should be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions in the embodiments of the present application.
