Description

Hand-held cavity shadowless lamp

Technical field

Medical auxiliary equipment is the utility model is related to, more particularly, to a kind of hand-held cavity shadowless lamp.

Background technology

In clinical operation, operative site is illuminated commonly using shadowless lamp, eliminates shade as far as possible, by color distortion Degree is preferably minimized, so as to which most preferably observation small area, low contrast, structure of different depth in otch or body cavity is interlocked Object.Existing operation shadowless lamp is typically made up of single or multiple lamp holders, and lamp holder is connected by cantilever with fixator, Gu Determine on the track that device is fixed at the top of support, ceiling or ceiling；Lamp holder is moved by cantilever upper and lower, left and right, and cantilever encloses Rotated around fixator, and then adjust the irradiation position of shadowless lamp；And operation shadowless lamp is at the top of operator, rear Or side rear irradiation, head, hand and the operation apparatus of operator etc. may interfere shade, no shadow to operative site Lamp can not direct irradiation operative site.

In addition, it is aseptic area that existing operation shadowless lamp, which only has the sterile sleeve on lamp handle, whole lamp body is to have bacterium, Operating personnel easily touch bacteria district domain in operation causes operative site to pollute, and existing operation shadowless lamp is in operation Need repeatedly to adjust lamp handle and just can determine that optimum position, adjustment process is cumbersome, the operation for not knowing about shadowless lamp cantilevered construction It is not easy to operate for personnel；Meanwhile existing operation shadowless lamp and its cantilever are more heavy, space-consuming is big, very flexible, no It is easy to operate, therefore typically operated more by assistant, assistant's operation often can not accurately irradiate operative site, so as to cause nothing Method meets the requirement of operator, and for deep regional（As at the top of liver）Or there is barrier obstruction region（Above stomach bottom） Operation technique, be often unable to reach operation needed for illuminating effect, trouble is caused to operation, due to some natural cavities of human body （Anal tube, intestinal tube etc.）And human interstitial（The epiploic foramen, ischiorectal fossa etc.）Often structure small for mouth and large for cavity, carried out to its inside If do not expanded oral area during irradiation, it is difficult to which light is projected into cavity or inner space, preferably illumination effect is unable to reach Fruit, operation technique is influenceed, increase operation risk.

The content of the invention

The utility model purpose be to provide it is a kind of simple in construction, it is easy to operate, the hand-held cavity of good illumination effect without Shadow lamp.

To achieve the above object, the utility model can take following technical proposals：

Hand-held cavity shadowless lamp described in the utility model, including the handle with switch, connect in the handle front end Lamp socket is connected to, the circular lamp band being made up of shadowless lamp pearl is provided with the lamp socket, in the center position of the circular lamp band Being extended along its irradiation side has connecting rod, and connecting rod front end forward equalization, which is extended, three expansion support arms, described Expansion supporting arm front end is provided with flexible spherical protective cap, is respectively provided with each expansion support arm close to the spherical protective cap end of the flexibility There is one group of fixing bar for carrying tooth engaged, adjacent two bars that fix engage clamping.

The handle outer is set with non-slip rubber set.

The rear end of the handle is provided with baffle plate.

The utility model advantage be it is simple in construction, compact, flexible, it is easy to operate, can be directly hand-held by surgical staff, just In the region that accurately alignment needs to illuminate；Entirety can carry out aseptic process, not contaminated operation position；Lamp socket front end leads to Cross connecting rod and be connected with three expansion support arms, cavity or human interstitial's oral area can be expanded, and then project light beams upon cavity It is interior, direct irradiation operative site, increase light-inletting quantity, improve illuminating effect, while the cavity expanded can also increase operation behaviour Make space, be easy to follow-up operation technique.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model.

Fig. 2 is Fig. 1 A-A to sectional view.

Embodiment

As shown in Figure 1, 2, hand-held cavity shadowless lamp described in the utility model, including the handle 2 with switch 1, The front end of handle 2 is connected with lamp socket 3, and the circular lamp band 4 being made up of shadowless lamp pearl is provided with lamp socket 3, by switch 1 come control ring The open and close of shape light bar 4, being extended in the center position of circular lamp band 4 along its irradiation side has connecting rod 5, connecting rod 5 front end forward equalizations, which are extended, three expansion support arms 6, and expansion support arm 6 front end is provided with flexible spherical protective cap 7, prevented When expansion support arm 6 is goed deep into human body, cavity inwall is stabbed in front end；Close to flexible spherical protective cap 7 on each expansion support arm 6 End is provided with one group of fixing bar 8 for carrying tooth engaged, and adjacent two, which fix bar 8, engages clamping, and expansion support arm 6 has certain Elasticity, when the fixing bar 8 of its front end engages clamping, expansion support arm 6 front end is in tightening state, when fixing the opening of bar 8, expands The front end resilience of support arm 6 is opened to open.

Frictional force during to increase hand-held, prevents cavity shadowless lamp from sliding, and the outer cover of handle 2 is equipped with non-slip rubber set 9；For Further prevent that handle 2 is slipped when to external extraction cavity shadowless lamp, and baffle plate 10, baffle plate 10 are provided with the rear end of handle 2 It can be that screw-on is fixed on the rear end of handle 2, serve as the end cap of handle inner battery compartment.

In use, the fixing bar 8 for expanding support arm 6 front end is engaged into clamping first, then rule of thumb or imaging data Support arm 6 will be expanded deeply in patient body by holding handle 2, after depth needed for operation is deep into, the position expanded as needed, and hand Refer to the corresponding rear end of expansion support arm 6 of pressing, open the fixing bar 8 of its front end, so as under the rebound effect of expansion support arm 6 Cavity wall is strutted；Then, circular lamp band 4 is opened, makes the affected area of light source direct irradiation patient Yu, can be carried out afterwards follow-up Operation technique.
