Abstract
The utility model relates to medical machinery, and in particular relates to a laser hemostat. The laser hemostat is characterized in that a metal hemostat is arranged on the end part of a cable; and the metal hemostat is arranged on the cable through a buckle or a heat shrink tube. By adopting the technical scheme, the laser hemostat has the beneficial effects that the mode of laser hemostasis is completely changed, laser energy is converted into heat energy through a metal ball fixed at the head end of the laser cable, and the hemostasis function can be realized through direct contact of the metal ball by compressing bleeding tissues, so that the defects that existing hemostasis has an over small action area, the position of the best acting point and the action direction laser are difficult to accurately hold, and the compression action of the target tissue is deficient can be completely overcome. Multiple tests prove that the hemostat has a satisfactory hemostasis effect and exact action, is convenient to use, and completely solves the problem of poor hemostasis effect in current laser hemostasis.
Description
Technical field
This utility model relates to medical apparatus and instruments, relates in particular to the laser hemostasis device.
Background technology
The per urethra laser surgery is that the multiple urological diseases of present minimally-invasive treatment is (such as benign prostate hyperplasia, tumor of bladder, urethral stricture etc.) best operation method, but the active area that is projected on tissue owing to laser is limited, the position of the best use of point and the action direction of laser all are difficult to accurate assurance, add bleeding tissue is lacked contention effect, cause laser to organize hemorrhage haemostatic effect not good to trunk is hemorrhage with large tracts of land, this also is that one of key issue that solves is badly in need of in present per urethra laser surgery, but this is all lacked at present effective solution both at home and abroad.
The utility model content
The purpose of utility model: for a kind of laser hemostasis device is provided, this device can solve laser hemostasis hard problem in the laser class operation process.
In order to reach as above purpose, this utility model is taked following technical scheme: optical fiber end is equipped with the metal haemostat.
The further technical scheme of this utility model machine is that described metal haemostat comprises ballhead, and ballhead can be connected on the optical fiber.
The further technical scheme of this utility model machine is that described metal haemostat comprises ballhead, also comprises the outer segment that is attached thereto, and can be socketed on the optical fiber.
The further technical scheme of this utility model machine is that described metal haemostat is installed on the optical fiber by buckle or heat-shrink tube.
Adopt as above this utility model of technical scheme, have following beneficial effect: we thoroughly change the hemostasis pattern of laser, by a metal ball that is fixed on the laser fiber head end laser energy is converted to heat energy, and directly contact and oppress bleeding tissue realization hemostatic function by metal ball, thereby the active area of having avoided in the past laser hemostasis to exist fully is too small, the position of the best use of point and the action direction of laser all are difficult to accurate assurance, and shortage is to the shortcomings such as contention effect of destination organization, we have also successfully solved the fixation problem of this haemostat simultaneously, so that it is easy to use fast.
Confirm that through overtesting this haemostat haemostatic effect is satisfied, definite effect and easy to use, thoroughly solved the problem of present laser hemostasis poor effect.
Description of drawings
In order to further specify this utility model, further describe below in conjunction with accompanying drawing:
Fig. 1 is embodiment 1 structural representation of utility model;
Fig. 2 is embodiment 2 structural representations of utility model;
Fig. 3 is embodiment 3 structural representations of utility model;

Wherein: 1. metal haemostat; 2. buckle; 3. optical fiber.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described, embodiment does not consist of restriction of the present utility model:
The laser hemostasis device is assigned into the optical fiber head end, with the method for heat-shrink tube or other mechanical connections, the laser hemostasis device is fixed on the optical fiber head end.
In conjunction with Fig. 1, embodiment 1:
The further technical scheme of this utility model machine is that described metal haemostat 1 comprises ballhead, and ballhead can be connected on the optical fiber 3.Described metal haemostat 1 is installed on the optical fiber 3 by buckle 2 or heat-shrink tube.
In conjunction with Fig. 2, embodiment 2:
Embodiment and described metal haemostat 1 comprise ballhead, also comprise the outer segment that is attached thereto, and can be socketed on the optical fiber 3.
In conjunction with Fig. 3, embodiment 3:
The difference of embodiment 3 and embodiment 2 is that the shape of outer segment and external diameter are inconsistent.
In conjunction with Fig. 2, Fig. 4, Fig. 5, this three width of cloth figure has reflected a kind of embodiment of installing.
Mechanism of the present utility model is: the energy of laser is conduction energy transform into heat energy on the blood coagulation head directly.Operating temperature is between 120 ℃-200 ℃.Material: heatproof is more than 1000 ℃, corrosion resistant metal, with rustless steel, titanium alloy for well.
Can use when damaged than trunk or arteries in operation.
As seen, fixed form that can't exhaustive metal haemostat 1, but similarly mode is all in protection domain of the present utility model.
More than show and described ultimate principle of the present utility model, principal character and advantage of the present utility model.Those skilled in the art should understand this utility model and not be restricted to the described embodiments; that describes in above-described embodiment and the description just illustrates principle of the present utility model; under the prerequisite that does not break away from this utility model spirit and scope; this utility model also has various changes and modifications, and these changes and improvements all fall in the claimed scope.
