Abstract

The utility model relates to a dilator used for a recta exposed at the operative field. The utility model comprises a forceps-shaped structure which is composed of a forceps jaws and forceps handles. The utility model is characterized in that one forceps handle is integrated with the forceps jaw at the same side of the forceps handle, the junction of the two forceps handles and the forceps jaws are movably connected with a pin shaft, the symmetric positions of the inner sides of the two forceps handles are respectively movably connected with a pull rod, the other end of one pull rod and the other end of the other pull rod are coaxially movably connected with a telescopic rod, the other end of the telescopic rod and the two forceps jaws are respectively fixed at the pipe walls of three arc surfaces forming a circular pipe, the inner center place of which is provided with a pushing rod, and one end of which is a spherical probe. The utility model has the characteristics of simple structure, convenient operation, high safety, long service life, etc.

Description

Procteurynter

This utility model belongs to the medical operation utensil, specifically a kind ofly is used for per anum position when operation because of the narrow procteurynter of widening.

At present, the rectal cancer sickness rate increases, for example: for the swollen thing per anum excision of rectum, hemorrhoid operation is many to expose the art open country through artificial expansion anus, artificial drag hook, wastes time and energy, and exposes poor effect, not only bring difficulty to operation technique, and because of use dynamics inequality causes anal fissure easily, the sphincter muscle of rectum incontinence, even malpractice can appear.

The purpose of this utility model provides a kind of procteurynter that exposes the art open country by the expansion caliber fast.

The purpose of this utility model is achieved in that it comprises by two pincers of being with jaws the tong-like structure of being formed, a jaw that it is characterized in that clamping with its homonymy is structure as a whole, live and connect a bearing pin in joint portion between two pincers handles and jaw, on the symmetric position of two pincers handle inboards, live respectively and connect a pull bar, be connected with an expansion link in the coaxial work of the other end of two pull bars, the other end of this expansion link and two jaws are separately fixed on the tube wall of three cambered surfaces that constitute pipe, are provided with the pushing ram that an end is the sphere contact at the heart place of pipe.Before operation, earlier the procteurynter of this structure sphere contact by the pipe end is inserted anus at leisure, extract the sphere contact out by pushing ram, tighten up two pincers handles on the dilator with hands then, then open two jaws and drive three sections tube walls forming pipe and pipe is expanded outwardly to the expansion link that pincers move direction, as required can be in 10 seconds with proctectasia to the 60-80 millimeter, thereby increased operation art open country.

The end work that this utility model is included in above-mentioned one of them pincers handle is connected with a spacing wiper, and same position of another pincers handle is provided with can be along the groove of spacing wiper slip and band holding screw.

This utility model also is included in two pincers being symmetrically arranged with the contacted spring leaf in an end on the inboard same position.

This utility model is owing to provide a kind of per anum position to excise the special implement that exposes the art open country when rectum swells thing, can expand anus fast, therefore reduced operating time, reduced widely because of operation causes that the art open country is hemorrhage, the generation of anal fissure even sphincter muscle of rectum incontinence accident rate.Characteristics such as that this utility model also has is simple in structure, esy to use, safe and reliable, long service life, applied range.

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is that stereochemical structure of the present utility model is launched simplified schematic diagram

By shown in Figure 1, among the figure be one by two the band jaws 2 pincers the 8 tong-like structures of being formed, these pincers are structure as a whole the jaw with its homonymy, live and connect a bearing pin 5 in joint portion between two pincers handles and jaw, on the symmetric position of two pincers handle inboards, live respectively and connect a pull bar 7, be connected with an expansion link 6 in the coaxial work of the other end of two pull bars 7, the other end of this expansion link 6 and two jaws 2 are separately fixed on the tube wall of three rustless steel cambered surfaces that constitute pipe 1, are provided with the pushing ram 4 that an end is a sphere contact 3 at the heart place of pipe; In addition, live by bolt 12 and be connected with a spacing wiper 11 in the end of a pincers handle therein, and the same position of another pincers handle is provided with can be along the groove 10 of spacing wiper slip and band holding screw 9.Before operation, earlier the procteurynter of this structure sphere contact (can be coated with one deck lubricating oil in case of necessity on the sphere contact) by the pipe end is inserted anus at leisure, extract sphere contact 3 out by pushing ram 4, tighten up two pincers handles on the dilator with hands then, then open two jaws and drive three sections tube walls forming pipes to the expansion link 6 that pincers move direction, and pipe 1 is expanded outwardly, as required can be with proctectasia 60-80 millimeter in 10 seconds, then along spacing wiper 11 sliding clamps last groove 10, when the expansion of this pipe appeared the wild size of art and is fit to, the holding screw 9 on the fastening groove can be located.Postoperative can take off this procteurynter by aforesaid reverse operation again.In addition, for the ease of this structure is quickly recovered to initial condition, then on the same position of two pincers handle inboards, be symmetrically arranged with the contacted spring leaf 13 in an end, when pipe is expansion state, two spring leafs are compressed, when postoperative time spent not, then two spring leafs recover strains and pipe are shrunk to initial condition.

Claims

1, a kind of procteurynter that is used to expose the art open country, it comprises by two pincers of being with jaws the tong-like structure of being formed, a jaw that it is characterized in that clamping with its homonymy is structure as a whole, live and connect a bearing pin in joint portion between two pincers handles and jaw, on the symmetric position of two pincers handle inboards, live respectively and connect a pull bar, be connected with an expansion link in the coaxial work of the other end of two pull bars, the other end of this expansion link and two jaws are separately fixed on the tube wall of three cambered surfaces that constitute pipe, and being provided with an end at the heart place of pipe is the pushing ram of sphere probe.

2, procteurynter according to claim 1 is characterized in that the end work of a pincers handle is connected with a spacing wiper therein, and the same position of another pincers handle is provided with can be along the groove of spacing wiper slip and band holding screw.
